Added text (component id) to cone/circle symbol symbolizing pose data from that component in 3D view.

Unified all object selections in 3D view via right-mouse-click, and added mouse-based terrain translation/rotation.

Windows build improvements

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.

Fixed Windows compilation and unified serial port baud rate support

This commit unifies the supported baud rates completely across QGC and OSes.

Fixed error (in VS2010) about lacking a return value introduced in 6a55b6cd.
