Finally resolved waypoint positioning issues, 2D and 3D map work now nicely together with less flicker

Fixed roll angle in Google earth, still not smooth. Fixed a number of threading issues. Fixed all custom widget related bugs. Improved MAVLink decoder. Reduced CPU usage substantially across all views

Small usability fixes for the Google Earth view, is now more convenient to use. Editing now only possible in edit mode, prevents false edits

Improved Google Earth interface, clearing trails works, switching views works (but is not yet perfect), switching editing mode on/off works

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

Fixed initialization of Google Earth, works now flawlessly. Further improvements needed on simulation link and Google Earth JavaScript.

YEEHAY! First working version of Google Earth direct interface - initialization is not perfect yet, current the user first has to ignore a number of script errors.
