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

Runtime issues resolved, quick application startup and good runtime stats: 0.3% load in idle mode, 15% load showing map and UAS list. Map has a zooming issue, but should be resolvable

Cleaned up serial port libs, activated mav visualization on map (still debugging), fixed standalone MAVLink generator

Added proper support for fullscreen mode, fixed issue with window state update on perspective change

Removed SLUGS' PID form to give way to the parameter interface. Replaced Old SLUGS messages for their common equivalents. Hunting bug in Home Position in MapControl

Made MAVLink parser aware of line breaks in comments, added new servo output packet to QGC and simulation, enabled servo output display in new Actuator View (previous Payload view)
