Updated repository URL and checkout instructions in the readme.

Updated the outdated OpenGL headers in Windows SDK. Fixes compilation on Windows.

Oops, forgot to update gfxlib for the renaming of endian.h to borendian.h.

Renamed endian.h to borendian.h to prevent clashing with system headers.

Silenced "ambiguous else" compiler warning on Wii.

Added support for alternative video.txt based on the platform.

Several interdependent changes that I've accumulated over the last 2 months:

Windows:
* OpenGL functions are now loaded dynamically.

Linux:
* Static linking of SDL is disabled because it causes problems on Ubuntu 10.10 RC.

Wii:
* Modularized the video backend so that it's independent from the engine.
* Restructuring and optimization of video code.
* Added brightness/gamma correction using the TEV unit that works in all color modes (and it's fast!)

OpenGL:
* Moved code to a separate file, opengl.c.
* Added brightness/gamma correction using GLSL that works in all color modes (confirmed to work but not yet used by the engine)
* Added support for 8-bit indexed textures using GLSL, disabled for now because it causes problems in conjunction with bilinear filtering.
* Lots of other changes that I don't remember.

Added new cross compiler for windows on mac os.

Added preprocessor switch to exclude libvorbis warnings.

Some quick corrections. Jumpmove code can probably be optimized, but works as intended.
