c486a9ee81 Remove redundant duplicate pressure samples
At least the Suunto pressure transmitter seems to be pretty
"quantisized", and it will send identical samples for a while until the
pressure changes enough.  Then subsurface gives this silly flat line
with a sudden jump downwards, which *could* be you suddenly taking a
deep breath after holding it for a while, but almost certainly it's a
sensor issue.

So just remove successive identical pressure readings.  They aren't
interesting, and subsurface will actually do a good job of interpolating
it according to SAC rate instead.  And they just make the XML look
worse.

1268e0d225 Show dives "latest-first" by default
You can still order them by date by just setting the sort order on the
date column, but normally you'd be more interested in the most recent
dives.

I tried to just scroll down to the last ones automatically instead, but
gtk makes that *really* hard to do.  If you do it in the natural place
for it, the scroll bar wll show up later and then cover up the last
entry anyway.  So you'd have to do some crazy expose event thing or
something.  Which may be the right thing to do eventually anyway, but
not worth the pain right now.

f967d6fb26 Fix the stupid gtk combo box text reset issue for real
Lubomir's solution to fill them with a newline doesn't work.  Well, it
may work on some versions of gtk, but on mine it just results in an ugly
box for the control character '000a' that tries to show the newline.

So this is a third approach: if we reset the text to empty, first set it
to space (to clear it), and then set it to empty.  That seems to work on
at least one version of gtk, and doesn't have the problem with the space
*remaining* when you cut-and-paste something into the combo box.

Let's see if it breaks anything else, but at worst it should be no worse
than the old "set it to space" approach - iow the combo box might
remember the space, but at least not some random data from the previous
dive that it happened to show.

Lovely gtk bugs.

5c2fca2620 Save cylinder O2/He content after the cylinder type description
This changes the save format xml to be a bit more readable: instead of
putting the gasmix first, put the cylinder type (size, workpressure and
description) first, then gasmix, then pressure details.

It makes no difference for machine parsing, but I think it's a lot more
logical for humans that actually look at the xml file.  And we really do
want to make the xml file readable by humans.

b4938ec2de Make the sample-vs-cylinder pressure check more liberal
This makes it consider them to be identical if they are within half a
bar of each other.  If you edit the pressures by hand and set them to
the same bar pressure as the samples, they may not be identical to the
last milli-bar, but clearly the manually entered cylinder pressure isn't
significantly different from the sample data, so consider it redundant.

We do want manual overrides of cylinder pressures to take precedence
over sample data (as Dirk so eloquently puts it, some dive computers
really don't have very reliable sample data), but at the same time the
sample data is the one we are expecting to be fairly accurate.  The
starting and ending pressure overrides are for when there is no sample
data, or when the sample data is totally wrong for some reason.

This grays out the pressure settings in the cylinder editing widget if
the pressure data has been taken from the samples.  You can still
manually override the data, but you now need to enable that manual
override explicitly.

This makes the semantics of editing start/end pressures of dives with
pressure sample data a bit more intuitive, I think.

NOTE! When *editing* the cylinder data, the only thing shown is the
non-sample pressure.  So the cylinder editing widget will show zero for
start/end pressure for a dive that has pressure saples without any

This is intentional, so that you can clearly see that this is not a set
value.  But it may be that we should gray out the spinputton and have an
"edit value" checkbox or something to make it really obvious.

0089dd8819 Don't save cylinder start/end pressures unless set by hand
Keep the sample pressure start/end data separate from the overall
cylinder start/end data - and clean the overall cylinder start/end data
if it matches the samples exactly to avoid the redundancy.

This breaks all the SAC calculations etc, which expect the cylinder
pressures to always be in the cylinder data.  I'll fix that up
separately.

The reason for this is that we really want to keep the manually entered
data separate: the pressure plotting doesn't need the confusion, and
considers end-point data (with interpolation) very different from sample
data.  Also, we do not want to pollute the xml save-file with data that
is computed.

c52b95d502 Improve tank pressure plot for computers that create "gaschange" events
This was exposed by the test dives, but it shows up in small ways with
real dives from some dive computers like the Suunto Vyper Air.

We now insert synthetic plot_info entries that match the gas change event;
to make this look smoother we insert either two events (one for the old
tank, one a second later for the new tank) if there is no sample at the
time of the event, or one additional event (and move the real sample back
by one second) if there is a sample at the time of the event.

This does expose another issue with some dives from Linus' computer where
the pressure in the samples dips below the end pressure noted for the tank
- which creates an odd "yellow up-tick" at the end of using the first tank
in the plot. Maybe we should not insert a synthetic "last of old tank"
event if we have a sample with valid pressure in the last NN seconds
before the gas change?

e810d211a6 Work around some gtk oddity with gtk_combo_box_entries and empty text
Setting the gtk_combo_box_entry test to th eempty string doesn't "take":
the old text remains.  Which does all kinds of funky things when you
switch between dives, and the location (or buddy or divemaster) entry
contains some random stale entry from another dive.

This works around it by using a string with a single space in it
instead, and then removing the space when reading.  Not pretty, and
certainly not correct, but it pinpoints the odd behavior.  I'm sure
somebody will figure out what the magic gtk incantation is for this.

Also remove the never-used flags for whether the entries have changed.
They were designed to be set by change callbacks, but we never bothered
with it, and just always read the value of the entries instead.
