Linus Torvalds 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).

Half-arsed divelog software in C.

I'm tired of java programs that don't work etc.

License: GPLv2

You need libxml2-devel and gtk2-devel to build this.

Usage:

	make
	./divelog dives/*.xml

to see my dives (with no notes or commentary).

There's a lot of duplicates in there, and divelog will de-duplicate the
ones that are exactly the same (just because they were imported multiple
times).  But at least two of the dives have duplicates that were edited
by Dirk in the Suunto Dive Manager, so they don't trigger the "exact
duplicates" match.

WARNING! I wasn't kidding when I said that I've done this by reading
gtk2 tutorials as I've gone along.  If somebody is more comfortable with
gtk, feel free to send me (signed-off) patches.

Just as an example of the extreme hackiness of the code, I don't even
bother connecting a signal for the "somebody edited the dive info"
cases.  I just save/restore the dive info every single time you switch
dives.  Christ! That's truly lame.

Also, I don't actually integrate directly with libdivecomputer, I just
read the XML files it can spit out.  But I included my own raw dive
profile xml files for anybody who isn't a diver, but decides that they
want to educate me in gtk.

NOTE! Some of the dives are pretty pitiful.  All the last dives are from
my divemaster course, so they are from following open water students
along (many of them the confined*water dives).  There a lot of the
action is at the surface, so some of the "dives" are 4ft deep and 2min
long.
