Include images in profile

Browse source 
This adds an entry to the dive list context menu to load images. The user
can select image files and set a time offset to align camera and dive
computer clocks.

Using the exif time stamp the images are tried to match to the times of
the selected dives (with a grace period of an hour before and after the
dive).  Upon success an event of type 123 is created per image with the
string value being the path to the image.  Those images are displayed as
thumbnails in the profile. If the matching dive does not yet have a geo
location specified but the image provides one it is copied to the dive
(making the camera a poor man's companion app).

This patch includes easyexif https://code.google.com/p/easyexif/ which is
originally under a New BSD License to parse the image meta data.

This commit includes a new test dive dives/test31.xml with a matching
image wreck.jpg to try out the functionallity.

Obvious to do's:
Have images on the map
Have the images clickable
Have a proper picture viewer
Give visual reference for image time shifting.
Use the new profile
