af290d5eb2 Add typical 0 to 5 star rating for dives
This works ok-ish, but doesn't allow us to click on the stars and edit
them in the divelist, which a user might expect to be able to do - in
most "star rating UIs" you simply click on the n-th star to set that
rating. Here you need to edit the dive and pick the rating from a drop
down menu.

Minor oddity: you can actually (if you force it) write anything you want
into the star rating. But anything that isn't one of the predefined
strings simply results in a zero star rating.

Overall the UI feels a bit... forced. But I think this is quite useful
anyway.

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.

0f9d1757a4 Don't drop precision from floating point GP coordinates
Using '%f' limits the precision to 6 decimals, which may well be
perfectly ok.  But at least in theory you *could* have higher precision,
and gps units will report it, so don't mindlessly limit us to what %f
shows.

This arbitrarily uses '%.12g' instead.  %g will drop excess zeroes at
the end, so it actually results in the same (or shorter) ascii
representation unless you have the extra precision.

5804c2970e Support gps coordinates for the location info
Sadly, no way to show them yet.  But it would be nice to let people
enter them (and it would be doubly nice to have a dive computer that
does it at the surface), and then perhaps just do the "point browser at
google maps" thing.

Saving/parsing tested by hand-feeding the location of Enenui (Molokini
Crater) from google maps by hand into my divelog.

3a6652634b Rename the project 'subsurface'
I never really liked 'diveclog' as a name - it's not like the C part is
all that important.  And while I could try to just make up another slang
word for despicable person (in the tradition of naming all my projects
after myself), I just can't see it.

0c4e1697db Be more careful about unit changes
When we change units, we need to flush any currently active dive
information in the old units, and then carefully reload it in the new
units.

Otherwise crazy stuff happens - like having current cylinder working
pressure values that are in PSI because that *used* to be the output
unit, but then interpreting those values as BAR, because we changed the
units.

Also, since we now properly import working pressure from Diving Log,
stop importing the (useless) cylinder description.  The Diving Log
cylinder descriptions are things like "Alu" or "Steel".  We're better
off just making up our own.

Finally, since Diving Log has cylinder size in metric, make sure that we
do the "match standard cylinder sizes" *after* we've done all the
cylinder size conversions to proper units.

b17c7f0709 Now that we don't mess up import, we can save the cylinder working pressure
We used to have the heuristic that if we saw a cylinder working
pressure, then the cylinder size would be in cuft.  Which meant that we
couldn't export our working pressures, because it would mess things up
on import.

But working pressure is actually nice to know, if you ever work with
cylinders in imperial units.  So now that the import is fixed, add the
working pressure to the export.

067506038a Rename 'cylinder.c' as 'equipment.c'
Make it about general equipment management, and start hooking up
functions to show new equipment information when changing dives (and to
flush changes to equipment information for the previously active dive).

Nothing is hooked up yet, and it's now showing just one (really big)
cylinder choice, so this is all broken.  But it should make it possible
to at least get somewhere some day.

04c98344b3 Turn dive depth, temperature and duration into xml attributes
This makes the xml save-file look way nicer: it's both smaller and
better organized.  Using individual xml nodes for random small details
is silly.

The duration even parses exactly the same, because it still ends up
being '.depth.duration' (now it's the 'duration' attribute of the dive
node, it used to be the 'duration' child node of the dive node).

5f79a804b9 Sanitize and fix cylinder pressure overview
Doing per-dive cylinder start/end pressures is insane, when we can have
up to eight cylinders.  The cylinder start/end pressure cannot be per
dive, it needs to be per cylinder.

This makes the save format cleaner too, we have all the cylinder data in

f8de487c2f Make a guess at the cylinder description from the size and pressure
I'll want to also add a way to override/set the cylinder type: both
manually by just setting a size in liters, and by picking from some list
of standard cylinder sizes.

For example, it looks like most of my dives are marked as having
12-liter cylinders.  That is probably some default from Suunto Dive
Manager, or from whatever Dirk did.  It's almost certainly not right for
any of them: as far as I know, the standard cylinders for Lahaina Divers
(which is likely most of the warm water dives) are AL72's for air, and
AL80's for Nitrox.

That would be a 10L and a 11.1L tank respectively, afaik.  I don't know
what a 12-liter tank would be or where that size comes from.

Anyway, the LP85+ tank designation for some of the dives looks more
likely: that's one of the common sizes I've used for local dives.  So
the size of that thing is much more probably correct.

ecff0922d4 Don't save cylinder working pressure
It was a mistake to save it - and I did it just because other dive
managers did.  It's a totally nonsensical measure, and nobody cares.
The only thing that matters is the size of the cylinder, and the
*actual* pressures.  Those give actual air consumption numbers, and are
meaningful and unambiguous.

So the "working pressure" for a cylinder is pointless except for two
things:

 - if you don't know the actual physical size, you need the "working
   pressure" along with the air size (eg "85 cuft") in order to compute
   the physical size.  So we do use the working pressure on *input* from
   systems that report cylinder sizes that way.

 - People may well want to know what kind of cylinder they were diving,
   and again, you can make a good guess about this from the working
   pressure.  So saving information like "HP100+" for the cylinder would
   be a good thing.

But notice how in neither case do we actually want to save the working
pressure itself.  And in fact saving it actually makes the output format
ambiguous: if we give both size and working pressure, what does 'size'
mean? Is it physical size in liters, or air size in cu ft?

So saving working pressure is just wrong. Get rid of it.

I'm going to add some kind of "cylinder description" thing, which we can
save instead (and perhaps guess standard cylinders from input like the
working pressure from dive logs that don't do this sanely - which is all
of them, as far as I can tell).

It never actually triggered anything for me, but any buffered data might
be lost, especially if you force-exit the application after saving a

When we see a number like 23.145, we'd better always also see a unit.

Be more careful with FP conversions, and with the Kelvin<->C offset.
And make sure to use the same names when saving as when parsing.

Now when we save a set of dives, then re-load them, and save again, the
second save image is identical to the first one.

Of course, we don't actually save everything we load, so we still do
lose information when we load and then save the result.  But at least we
