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

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
