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.

Removed outdated MAVLINK v0.9 version as QGC does not work with this version.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.

Compilation on Windows VS2010 now properly copies necessary support libraries to the /debug and /release directories based on which is currently building. These copies are also only done if they are necessary.
I removed copying of the plugins folder from Qt to the executable directory as I don't believe it's necessary anymore.

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

Compiling 32bit on Mac OS again to re-gain Google Earth support, fixed MAP API KEY to re-enable Google Maps support, added Asctec Hex rotor and SenseSoar models

Auto-deleting unwanted build files from release directory, build script now perfectly creates a distribution-ready folder structure.
