Update 3.3.18

+ Some changes regarding adding and modifying image directions (new toolbar button and menu option for adding image direction and possibility to add/modify image direction by dragging image markers on the map)
+ Optimized display of image direction of focused image (auto adjust size to map)
+ Point of view coordinates now editable in dialog
+ Faces will now be read also from Google Picasa. Renaming image files in GeoSetter will adjust Picasa database and therefore keep face assignments in touch.
