Fixed data stream interface widgets - now transmitting after 400 ms user timeout. No more data stream request flooding

Started parameter interface refactoring to adhere to MVC design pattern. Working on getting custom widgets completely up and running

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

Improved line chart, brought back movement on HUD (but still looks somewhat wrong on the dials). Fixed logging for ground time mode

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.
