TOLTECS: - Added menu system prototype (may change later)

- Added movie player (still incomplete, sound is not yet implemented)
Both are not yet hooked to the engine.
- Added code for microtile arrays (from the SEL - Simple DirectMedia Layer Extension Library project), under the LGPL
This will be used as dirty rectangle "manager". This is experimental for now, it may be removed later.
