For reasons I don't understand, the device pixel ratio was taken into account
twice. And as a result the transformation applied to the profile made us show
only the top left part of it - but enlarged (depending on the DPR).
This code fixes that problem by simply forcing the transformation used by the
painter to be the identity matrix. I worry that this could be wrong in some
situations, but for now it seems to fix the problem.

This way we can have attachment of fairly arbitrary size (which should
be extremely useful for long libdivecomputer logs). This isn't quite as
intuitive as what we did before - the user needs to pick an email app to
share with), but that doesn't seem too bad - and also... this way they
can share logfiles via Dropbox or analyze them in other apps).
If the file share fails for some reason, we fall back to the old method
with passing the combined logs as body to the support message.
As an implementation detail this keeps the correct path for the app log file around
(this was stupidly overwritten before).

When in the planner, ESC should cancel the plan.
However, when the user manipulates the dive-handles in the
profile and presses ESC, first nothing happens, then an obscure
message appears.
The reason is that ESC "shortcuts" are introduced in two places.
To fix this, remove the ESC shortcut in the profile (the planner
widget cancels the plan anyway) and replace all the shortcuts in
the profile with a simple override of the keyPressEvent().
The latter is not strictly necessary, but hopefully avoids further
complications with multiple shortcuts. And the code is easier
to follow too.

When the file system of the Zurich gets full, the only way to continue to
download from it, is to disconnect and reconnect the dive computer (which
resets the FAT file system that it emulates to 'empty').
This solution is rather hacky and weird because it does a hard count down in a
busy loop, but given the narrow use case, this may be acceptable.
This also adds support for the UEMIS_DIVE_OFFSET environment variable that
allows the user to skip dives on the device.

This was a user request: Sort bar charts by height of the bars.
Obviously, this can only work for categorical charts, not for
histograms.
The UI is a break from the old concept: the sorting is chosen
based on the chart, whereas for the rest of the features, the
viable charts are presented based on the binning, etc.
I found it confusing to have the possible charts be selected
based on sorting. I.e. if a non-bin sort mode is selected,
the histogram charts disappear. On the flip side, this would
be more consistent. We can change it later.
For value-based bar charts, there are three sort modes: by
bin, by count (i.e. number of dives in that bar) and by
value (i.e. length of the bar). This hopefully satisfies all
needs.

The font-size in printed profiles is based on the size of the profile

Matter of fact, when making shrinking the height of the window to

When merging cylinders pressures derived from samples were taken

pressure was manually set for the cylinder of the first part of
