Changed waypoint list file format (old files are not compatible anymore!), added file version check, now all waypoint entries should have an entry in the waypoint list file - although qgc does not use/read the orbit_direction and param1 fields. QGC writes the value of orbit into param1 and 0 to orbit_direction (this should and will be changed later!)

Added not yet working version of logging / log replay, fixed ALL bugs in main window, enabled full persistence in main window and serial link.

fixed some waypoint initialization problems (action and frame were not updated correctly in the waypoint list when read from the waypointplanner

Major refactoring of the waypoint code. The new design fits the model-view-controller pattern better.

(cherry picked from commit ed0fd7c1)

UASWaypointManager now implements the protocol described in http://qgroundcontrol.org/waypoint_protocol
