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

Cleaned up and commented major code parts. Refactoring HDD and HSI widgets to support QGraphicsView drag-and-drop, tested multi-MAV support more intensely, currently adding the system coloring to all widgets

Cleaned up communication structure significantly, should now be easier to add new links. Signal bytesReceived(link, QByteArray) is now only way to pass on newly received data

Added MAVLinkLight as an example how to add new protocols, it is currently not an actual implemented protocol

Started to add support for autopilot firmware updates, added Linux compile instructions, fixed date in mavlink.h to english independent of OS language settings

Added support for MAVLink XML inclusion, added support for multiple Autopilots, improved protocol generation

Pushed implementation of parameter settings, almost done. Added many new MAVLink messages needed for interaction with IMU
