Substantially bugfixed and improved deactivation/activation and persistence of widgets. A lot of testing of Google Earth view, only minor improvements

Significantly bugfixed persistence and link adding/removal. Not yet fully there, but getting closer to release

QGroundControl now compiles under Visual Studio 9 / 2008. Google Earth support for Windows close to work.

added forwardMessage() function to send out Global Position over serial links
that are not part of the UAS's link list.

Still working on having independent builds for each MAV, most of the work is done, only Central Widgets remain to be instantiated and menu-controlled based on the autopilot

VERY UNSTABLE. Working on changing the way widgets are constructed and shown now based on the Detected autopilot. The basic scaffolding is in place still needs a lot of work.

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

Fixed imagery rendering issues. Robot position in Pixhawk3DWidget is now derived from the global pose (lat/lon/alt) instead of the local pose.

corrected a compile warning in Wayppoint.cc, made adaptions to Freenect for the current revision of the code (update libfreenect repository!), commented out pixhawk poi mavlink code - needs fixing

Still need to add uas connections. New osgwidget inherits from
qgraphicsview to expose more functionality to qt. Map3d.ui contains
the graphics view and some buttons. Currently runs yahoo_heightfield
by default. Make sure you run qgroundcontrol fromt the top dir or
it will seg fault, :-). I'll add some error handling soon.
