We had two totally different usage cases for "get_volume_string()": one
that did the obvious "show this volume as a string", and one that tried
to show a cylinder size.
The function used a magic third argument (the working pressure of the
cylinder) to distinguish between the two cases, but it still got it
wrong.
A metric cylinder doesn't necessarily have a working pressure at all,
and the size is a wet size in liters. We'd pass in zero as the working
pressure, and if the volume units were set to cubic feet, the logic in
"get_volume_string()" would happily convert the metric wet size into the
wet size in cubic feet.
But that's completely wrong. An imperial cylinder size simply isn't a
wet size. If you don't have a working pressure, you cannot convert the
cylinder size to cubic feet. End of story.
So instead of having "get_volume_string()" have magical behavior
depending on working pressure, and getting it wrong anyway, just make
get_volume_string do a pure volume conversion, and create a whole new
function for showing the size of a cylinder.
Now, if the cylinder doesn't have a working pressure, we just show the
metric size, even if the user had asked for cubic feet.

When there is only one gasmix in the list we should show the icon that tells the
user that they can't remove the last gasmix from the list.

For the proper calculation, we need to take salinity and surface pressure
into account (rather than depth = bar * 10 - 10)

If we remove a cylidner for a unique gas and that is allowable, then don't
try to copy from cylinder with index same_gas (which is still -1).

Another change to make it easier to program the mobile ui. This was a
fairly easy patch: just moved the contents of the file and fixed the
includes.

Still trying to make it easier for the Mobile Port:
This patch is a bit bigger than I hopped, but it was the smallest that I
could get.
A lot of TODO items where added where I broke the code because the current
implementation would break the QML implementtion on the designer. I'll
most probably fix those myself when I finish the transition to the models
to the new folder.
I only moved both models at once because there's an interdependency
between them (seems inevitable, tough, but I'll take a better look at it
later).
