4c04fe5316 Add all dive computers to the device_info_list
Calling set_dc_nickname() only added a new entry if there was a conflict
with an existing one - which works fine if we are reading a file saved by
Subsurface, as there the device_info_list is populated at parse time, but
fails for data imported from other sources.

Fixes #74

cd5c61e102 Don't use gtk_show_about_dialog() for the about dialog
There is a bug in GTK 2.2x where the links in the about dialog
(and URI's in general) do not work on Windows. To solve that
we add the OS specific method subsurface_launch_for_uri().
But to dispatch URI requests from the about dialog we need to
set a hook either with gtk_about_dialog_set_url_hook() (which is
deprecated from 2.24) or using signals like "activate-link".

One problem with the "activate-link" signal thought is that
we need to have a reference of an about dialog to pass to
g_signal_connect(). So instead of using gtk_show_about_dialog()
let's manage a dialog ourself with gtk_about_dialog_new(),
gtk_dialog_run(), gtk_widget_destroy().

Other changes:
- for GTK _bellow_ (but not including) 2.24 use
gtk_about_dialog_set_url_hook()
- use g_object_set() which is a convenient replacement for
the varargs list in gtk_show_about_dialog() (also makes the diff smaller).

739ea9989c gtk-gui: Check if the GTK version is lower than 2.24 for the about dialog
The about dialog URI calls are broken on Windows, therefore we needed
a way to override the default URI method. On versions bellow or equal to
GTK 2.24 this is possible with gtk_about_dialog_set_url_hook(),
which on the other hand is deprecated for newer GTK versions.

7024930530 Properly destroy the cairo context when we're done with it
Henrik reports that on OSX, not destroying the cairo context results in
a corrupted profile display.  It seems to just leak memory on Linux.

For gtk3, the cairo context is embedded in the GtkDrawable, for gtk2 we
need to create and destroy it appropriately.  Although maybe we could
just make it static instead of creating/destroying it all the time.

Anyway, this goes back to the old cairo destroy logic for gtk2.

3ab3e4e892 Show Gradient Factors in plot when showing calculated ceilings
This adds the GFlow/high values used to calculate the ceiling (if any).
Right now it shows those numbers even if at no point of the dive there was
an actual ceiling (but only if showing the ceiling itself is enabled).

This should make it easier to for the user to make sense of the calculated
ceiling, especially if posting screen shots.

As an aside - for some dive computers like the OSTC and the Shearwaters we
should be able to also plot the GF used by its calculation which might be
interesting for comparison purposes, as both of them also give us the
ceiling (lowest deco stop) calculated during the dive..

This all came about because I was trying to explain on G+ what an

gtk at all.  Google and the gtk migration guide are almost useless, and
the gtk2 documentation itself actually uses the fields directly without
any accessor functions in several places.

b8efe709a8 Remove saving of dive computer nicnames in system config
We save the (more complete) dive computer information in the XML file
with serial numbers and firmware version if we know about them, so using
a complicated string in the system config was redundant and confusing.

So remove that code.

NOTE! Since the dive computer nicknames are now only saved if the XML
file is saved, we also mark the dive list "changed" when we edit the
nicknames.  That way we'll be prompted to save things before exiting,
even if we don't actually edit any actual dive data.

52050fdc92 Save all dive computer nicknames - whether used or not
We used to save dive computer information only if that dive computer was
actually used in any of the dives we saved.  But we can simplify the
code if we just always save any dive computers we know about.  And it
does allow for some usage cases where you have nicknames for other
peoples computers that you may not actively use, but you want to see if
you end up loading multiple XML files in one go.

So there's just no compelling reason to not just save all the info we
have.  And this will make it less painful to remove the "use system
config for dive computer nicknames", because you can also use this to
continue to gather dive computer info in a separate XML file if you want
to.

4982389ca7 Fix setting of the dive_table.preexisting logic
The 'preexisting' value is used for downloading dives: we want to add
new dives but, but then compare those new dives against the
preexisting ones before we start sorting things and possibly merging
them.

However, the value was only updated sporadically, resulting in it
having stale information in it.  Which would cause problems
particularly if you deleted dives, so that the preexisting value would
point past the actual existing values!

So just update it unconditionally in dive_list_update_dives(), which
anything that changes the dive list is supposed to call in order to
display the changes anyway.

Also, just for safety, when removing a dive, put NULL in the last dive
table location.  Nobody should ever access past the end anyway (this
is enforced by 'get_dive()') but there are places that access the dive
list table directly, and the libdivecomputer download was one of
those.  No reason to leave stale dive pointers possibly around for
uses like that.

713c845e5a Add GPS icon to the location column for dive sites where we have GPS data
This replaces the really lame "italics text" from commit abe810ca1a29
("Mark locations that have GPS location data attached") with a marginally
less lame GPS icon.There's a reason why I am not making a living as
graphics artist. But I think this is a huge step forward from what we had
before...

The satellite.svg file is very loosely based on a different icon that I
found as public domain here http://www.clker.com/clipart-30400.html.
From that I created the PNG and then that was converted into the
GdkPixdata via gdk-pixbuf-csource; a rule for that was added to
the Makefile but commented out as I don't know if this tool will always be
available in the path. Having this icon included in the sources avoids
locating yet another icon file.

Better icons are certainly welcome!

2fb7aa1172 Attempt to override the URI handler in the about dialog
The previous patch in this series adds the function
subsurface_launch_for_uri(), which has to be called from the about
dialog instead of the default function for the URI calls to work
on Windows - i.e. opening links from the dialog.

gtk_about_dialog_set_url_hook() is a deprecated method, but seems
to be the only reasonable way to make the override between GTK 2.20 -
2.24 possible. The "activate-link" signal is recomended instead,
but is not portable for GTK bellow 2.24.

An alternative would be to somehow hack into the GtkAboutDialog
and override the callback for each clickable link.

This patch moves N2_IN_AIR from deco.c to dive.h as this is already used

respecifies N2_IN_AIR to a more correct value of 78,084%, the former one

c4ae58d589 gtk-gui.c: Move the download dialog related code to a new file
A new file download-dialog.c now contains all code related
to the download dialog, which was previously defined in gtk-gui.c.

Also, a new file callbacks-gtk.h now has two macros
OPTIONCALLBACK, UNITCALLBACK shared only between
download-dialog.c and gtk-gui.c.

8dea49ffe2 Clean up preference saving code
The old code (on purpose) didn't try to differentiate "nonexisting
boolean configuration" with "existing boolean configuration set to
false", which is problematic if we optimize the saving to not save
default preferences at all.

Which this does.

So in addition to the logic to know about default preferences, this has
to change the interfaces for the PREF_BOOL reading code so that you can
tell the difference between "no value" and "false".

And since the previous calling convention was an abomination of doing
pointer casting and having case-statements for the config types, change
that while at it.  Both from a usage perspective *and* from a back-end
perspective it is actually much simpler to just have different functions
for the string vs boolean config read/write versions.  The OSX versions
in particular end up being one-liners.

(The GConf library is a nightmare, and doesn't seem to have any way to
know whether a boolean value exists or not, so you have to read it as a
GConfVal and then turn it into a gboolean rather than just get the "oh,
it didn't exist" as an error value).

21f38190d3 Make the default preferences explicit
This makes it explicit what the default preferences are, so that we can
more easily avoid unnecessarily saving default settings.  It also makes
imperial metrics the default for the US (Burma and Liberia always get
forgotten!)

Right now we tend to be somewhat confused about defaults.  We do have
them, but then even if something has a default value, we tend to write
it out to the config file.  Which is not just unnecessary, but makes it
really hard to see after-the-fact whether the user actually wanted that
*specific* value, or whether they just wanted the default behavior.

So this prepares for having explicit configuration for when we want
something different than the defaults.
