Fix addStop to work as slot again

In order to call this as slot it needs to have defaults for all arguments.
So we need to change the gasmix into a pointer - which is actually better
as this allows to easily pass a NULL pointer when we want to continue to
use the previous gas.

Optionally strip diveplan to bare minimum

There are new check-boxes to modify the look of the diveplan in the notes.

The old behaviour appears with "verbatim display", others are shorter,
runtimes, stoplengths and transitions being optional.  Also round to full
meters and minutes to remove optical clutter.

To be done: Remember these setting in the config.

Rewrite dive edit logic

The existing code took an odd approach. It tried to change all selected
dives whenever the user edited a field, and kept all this backup data in
case the user rejected the edits.

This code takes the opposite approach. Only edit a copy of the selected
dive and then when the user accepts it, edit all the dives and when the
user rejects the edit simply redraw the screen (as all the "real" data is
still unchanged).

This not only saves quite a bit of code, it should be much easier to get
correct.

Admitedly this code will need quite a bit more testing to make sure it
works as intended, but as far as I can tell it already gets more scenarios
right than the previous implementation.

Add a picture_list struct

Add a picture_list struct that will hold all the pictures relative to a
dive. Before we used to hold events for the pictures, but an event is a
much bigger struct so this will save a bit of memory, and we will also
stop to use magic flags and special treatment for pictures on the dive
profile.

Break picture handling code from C++ to C.

This commit breaks the loading of images that were done in the divelist
into smaller bits. A bit of code refactor was done in order to correct the
placement of a few methods.

ShiftTimesDialog::EpochFromExiv got moved to Exif::epoch dive_add_picture
is now used instead of add_event picture_load_exif_data got implemented
using the old listview code.  dive_set_geodata_from_picture got
implemented using the old listview code.

Update the picture model to use the new picture function calls.

Update the picture model to use the new picture function calls, wich made
the code smaller and easyer to understand. AND as a plus, it doesn't use
the magic 123 identifier for pictures.  AND it correctly adds images
without timestamp to the list.
