Corrected the Windows Visual Studio compilation so that release builds no longer have a console or debugging macros while the debug builds have both.
Fixed indentation across all build scripts (.pro/.pri) to be 4-spaces and consistent.
Updated the README with proper Visual Studio compilation instructions for both VS2010 and VS2008.

Added remote OpenGL drawing in 3D view. Any external application can draw to the 3D view via the protobuf implementation of GLOverlay messages.

Removed outdated MAVLINK v0.9 version as QGC does not work with this version. Added feature to import COLLADA terrain model and visualize model in 3D view.

Added visualization of obstacles. Fixed relative font path issue in 3D widgets by using QFont within osgText::Font instead of using static font filename.

Re-enabled OSG support for Mac OS, for the 32bit build (64bit does not support Google Earth) the local 3D map is now enabled per default

Minor cleanup, fixed a bug where the serial port would not connect on first application launch on Linux

Set the remote address of the xbee via the xbeeconfiguration window and save last address in a txt file. Xbeelink ist still hardcoded to work with series2 xbees

Changed project file. Project can be included in VC with QTaddin such that moccing is not always performed

Still some Bugs. In VS2010 the RCC_DIR preprocessor define path is not used.
