I had to update some method calls in UASUnitTest.cc. I'd bet that some of the tests are wrong now because of it.

TODO: This should be altered to reuse stuff from qgroundcontrol.pro by including it instead of copy/paste.

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.
