Added angle conversion testing, added battery settings option, added option to set MAVLink ID of groundstation

Fully working waypoint interface, thoroughly tested. Active waypoint setting has to be debugged in the simulator, but works fine on real hardware

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

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

Added command to select target position for robot - command can be accessed via a right-click in the 3D View perspective --Lionel

Working on QGraphicsView-based local waypoints interface supporting drag-and-drop, commented code, fixed Google Maps interface, added mouse and SpinBox zoom to HSIWidget, fixed MAV-based coloring and stylesheets - MEGA COMMIT

Fixed Audio output on Linux, works now with systems flite version. Introduced two new alarm/notify sounds
