21.3: Fixed bug with taking photos from app.

21.2: Better error handling for route creation. Show messages on Goto page when switching to next waypoint or previous waypoint on a route. Pop up a dialog if an error occurs when taking a photo (rather than showing just a brief Toast message).

21.1: Added option to show your selected route on the map. When exporting waypoints to CSV file, also include the description. Added a north dot on the compass on the watch to make north more visible.
