destructor of UAS.cc

Erros casused by all of the mergedd branches are now fixed for qgroundcontrol.pro. Working on fixing the errors that now appeare in qgcunittest.pro.

Put libraries into one libs directory under qgroundcontrol. Changed the neccessary files with references to those libraries.

Added a unit test, setAirframeTest. Changed setAirframe function. Added an end_of_enum to the airframe enum.

Unit tests compile and run but still fail 4 tests. Segfault fixed which was caused by colors list in UASInterface.h.

qgcunittest.pro now compiles and runs as long as run in terminal in projcts->Run Settings is unchecked.

as long as the waypoint comes from the right systemID there is no
point rejecting it based on component ID. 

The current_partner_compid is also completely wrong in the code, so
checking it makes no sense anyway

Added remote OpenGL drawing in 3D view. Any external application can draw to the 3D view via the protobuf implementation of GLOverlay messages.

Introduced persistence in RGBDview, needs debugging, fixed a bug in param reading in the simulator, pushed message sender a bit forward, not working yet

Also updated all the units for the heartbeat values that are exposed to the realtime plotter to follow the suggestions laid out by the documentation for valueChanged().

Removed some dead code.
Added more valueChanged() signals to account for every data type. This moves the conversion over into the valueChanged receivers, which while it will require more slot-functions, makes it easier to add more code as any necessary conversion is done internally to the slot and so the signaler doesn't need to know the details.
I also added some more details on the types of units expected by valueChanged().

Exposed HEARTBEAT.system_status and HEARTBEAT.base_mode to the realtime plotter widget via the valueChanged signal.
