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 bugfixed persistence and link adding/removal. Not yet fully there, but getting closer to release

QGroundControl now compiles under Visual Studio 9 / 2008. Google Earth support for Windows close to work.

added forwardMessage() function to send out Global Position over serial links
that are not part of the UAS's link list.

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
