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.

Started to add support for autopilot firmware updates, added Linux compile instructions, fixed date in mavlink.h to english independent of OS language settings

This commit and the previous merge attempts to align my tree with upstream changes. It works for me but apologies in advance if i break anything
