Several changes and improvements:
- Details view: added Focal Length in 35 mm equivalent
- Tags view: a unique list of tags with a popover to jump into the different sections
- Map view:
- settings and info button instead of the segmented controls and the baloon on the pin
- added the direction of the camera when the picture was captured
- in the Address View (accessible by the Map one) direction, altitude and speed are added.
