Handle 'gas change' events correctly
Dirk wrote the multi-cylinder support assuming that the dive computer

what his Uemis does, and it makes sense for any dive computer that

However, the other case is a dive computer where the pressure samples
are all from cylinder 0, and any other cylinder will have the starting
and ending pressure set by hand. And the gas change events show when
the cylinder change happened.
So this creates a "turn gas change events into pressure sample fixups"

pressure analysis can alway sdo the right thing, regardless of how the

Plot tank pressures for multiple tanks
The code keeps track of the segments of time when a specific tank was used
and interpolates the pressure values for that tank based on a simulated
average SAC rate for the times in which no pressure readings are
available.
This changes the way we used to plot the pressure when only beginning and
end pressure of a tank are known; it used to be a straight line, now it is
a sloped line where the steepness of the slope is proportional to the
depth at that point - which is much more realistic.
We also plot the pressures in two colors now. The old green for pressure
data that came from the input file (that is not the same thing as saying
it came from the computer - divelog for example appear to create pressure
readings in the samples even if it only has beginning and end pressure).
Interpolated values are plotted in yellow. If you have a sub-standard dive
computer which has a frequently failing pressure sensor, you can now tell
the parts of the plot where data was missing and we are filling in.
The function that prints the pressure text labels had to be completely
redone as it previously assumed one tank for the whole dive and
simplisticly printed that tank's start and end pressure at the beginning
and end of the profile plot with the y-values being the maximum and
minimum pressure...

structure to keep track of the pressure information per segment - Linus

Add the ability to add new cylinders
This is totally useless since you cannot actually *edit* the resulting
new dive yet, but we'll get there. And this already conceptually shows
a capability that we didn't use to have with the old interface.

Start re-organizing the cylinder entry in equipment.c
This leaves the actual editing code unconnected, so now you can only see
the cylinder information, not actually edit it. However, with the big
re-organization I really do want to have this as a half-way point where
I have created the new cylinder tree-view.
I now need to connect the "add/edit" buttons to dialogs that then use
the editing widgets - so I've left that widget code around, because I'll
be able to reuse a lot of it. Not all, but the cylinder type model code
in particular will be re-used pretty much as-is.

Split up generic code to generate a gtk tree view column
We used to do this just for the dive list, but the new cylinder view
will want to do a lot of the same boilerplate gtk stuff, so make it a
bit more generic and move it to gtk-gui.c.

We forgot to pick up the 'value' field of a dive event
Just missed that one entirely in the xml parser for some reason.
Probably because the fields don't have much semantic meaning, so I
didn't even realize that I had missed one of the random integer values
in an event.
On my suunto, the 'value' field seems to contain things like the new
Oxygen percentage of a gas change event etc.
Distinguish internally between min pressure and end pressure
And don't artificially end dives on min pressure
This may be a problem for dive computers like Linus' Suunto Vyper Air
where the failure mode seems to be _high_ pressure readings (that's scary,
btw). If the transmitter fails at the end of the dive the pressure plot
ends with incorrect high pressure. But that's simply a bug with the dive
computer and not something that subsurface should hack around. Maybe we
should offer a way to edit the incorrect data points instead.
Always ending on the minimum pressure is definitely wrong as it causes
bogus plots when you do a valve shutdown during the dive (which means that
valid data gets plotted incorrectly).
We were missing the last sample (which is usually a fast ascent).
Also, reduced the velocity smoothing to 15 seconds as the 30 seconds were
hiding too much valid information
Correctly parse the braindamaged tank size information from uemis
Admittedly the cuft ratings are stupid, but still, it's not that hard.
In order to correctly describe a tank based on the cuft system you need to
know the cuft AND the working pressure. But the uemis Zurich always
assumes that the working pressure is 200bar. That's pretty close to
3000psi and therefore works "good enough" for Aluminum tanks - but in
general this will of course fail (e.g. for HP or LP tanks).
Yes Linus, gas pressure can indeed go up during a dive
At first glance it seems logical to make the ending pressure be the
lowest pressure observed during a dive. But if you do valve shut down
drills with a tech setup (where you have a fully redundant double
tank setup with two valves, two regulators and a manifold in between),
then you continue to breath from what is indeed the same "tank", but still
the valve on which your air pressure transmitter sits does get shut down
and de-pressurized. So your pressure goes down by quite a bit, and then
comes back up when the valve is turned back on.
And the ending pressure of the dive (which is used for things like the SAC
calculation) is indeed potentially higher than the lowest pressure
observed during a dive.
