Link to original bug (#657097)
Description
Currently the Empathy avatar can be chosen from the open-file-dialog as an image from the disk or a camera capture (if a camera was detected).
Improve Empathy's avatar chooser by presenting:
- a grid of standard or previously used avatars
- an option to get avatar from camera (if a camera was detected)
- an option to select another image
