Refactoring WP interface, somewhat brittle and untested at this point - use the master branch if you need stable code right now

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!)

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

separation of the view of the local operator of the view of the global operator adding the view of global operator.
add the functionality to draw a waypoints on the map when they are generated from widget waypointlist.

added functions to create global waypoinst, modifying the WaypointList class, MapWidget and MainWindows.

add the functionality to erase the list of Waypoint widget (WaypointView) from the button of the WaypointList widget

add widget WaypointView to widget WaypointList when create a waypoint with mouse over the map

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

Major cleanup of MainWindow constructor. All widgets have now the visible property set to false on its constructor

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