Refactoring WP interface, somewhat brittle and untested at this point - use the master branch if you need stable code right now

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

Added not yet working version of logging / log replay, fixed ALL bugs in main window, enabled full persistence in main window and serial link.

Fixed multi-thread message window bug, mainwindow should not hang any more on message windows from comm threads

First semi-usable version with new menu layout based on autopilot. Still very experimental. Current Bug: Linecharts do not work. Need to find out why

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

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 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

Made generator --pedantic GCC flag compatible/C89 compatible, fixed a bug where heartbeats where only sent to first link

Fixed object instantiation bug, started to implement QGroundControl-Server for online MAV visualization and control
