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)

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

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

Fixed initial startup bugs, cleaned up the activation-deactivation of update timers. Added initial instructions for new users.

Significantly improved plotting, now capturing data in linechart allows limmediate processing / analysis of the whole flight

Major cleanup of MainWindow constructor. All widgets have now the visible property set to false on its constructor
