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)
