Revamp of the video system in progress - adding support for multiple displays, multiple windows, and a full video mode selection API.

WARNING: None of the video drivers have been updated for the new API yet! The API is still under design and very fluid.

The code is now run through a consistent indent format:
indent -i4 -nut -nsc -br -ce

The headers are being converted to automatically generate doxygen documentation.
