Picture handling: when zooming thumbnail, put it in the foreground

This just seems to look much better.

Improve statistic on used gas

This raises the maximum number of gas mixes listed to 20 and also changes
the layout / design of the stats tab to make it much more attractive.

More layout work for stats tab

This finally gets me something that I like. The way the different boxes
get resized seems pleasant and intuitive. And it appears to do the right
thing on all platforms (I learned that having different levels of layout
nested creates no vertical offset on Linux/KDE, but a very ugly offset on
Mac, for example).

I know this is being redone, but the messed up tab order was driving me
insane when testing.

Don't ignore actual diveable mixes

Fist is really obvious. I quite regularly decompress using pure O2.
It's as good a last decompression gas as you get.

The second is a bit harder. There are very few that dive with 80%+ helium
in their mixes but they exist, and there are real weirdos that dive
heliox, so they are actual diveable gases too.

Create Dive Computer configuration dialog

Create a dialog for reading and writing settings to and
from dive computers, with a menu entry in MainWindow to
open the dialog.

I will build up on this dialog and change it as needed.

method used to detect the dive computer family. Detection is
now done using: dc_device_get_type.

This patch enables XML backup. We can now save the settings
to an XML file. Currently this backs up just the basic stuff
such as custom text, language and brightness.
