Break picture handling code from C++ to C.

Browse source 
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.
