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)

Added right-click option to select MAV, ensured that waypoints get updated properly on switching MAV

Cleaned up serial link handling, eliminated double menu entries and safeguarded the link list. Did intentionally not improve the object dependency issue, will work on that on a global scope

Working on better simulation implementation, fixed a bug where the port handle was not fully released

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

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

Added new options for windows serial port, fixed a number of bugs, added customizing options to instrument widgets
