Imports the current Win32 source for the pod-racing game 'Red Planet', built on the MUNGA engine and its L4 (Win32/DirectX) platform layer: - MUNGA / MUNGA_L4: cross-platform engine core and Win32 backend - RP / RP_L4: Red Planet game logic and Win32 application - DivLoader, Setup1: asset loader and installer project - lib, MUNGA_L4/openal, MUNGA_L4/sos: third-party audio dependencies Removed stale Subversion metadata and added .gitignore/.gitattributes.
