Initial implementation of Nitro Particles

- Drifting particles and mini turbo (sans extra spark particles)
- Slowdown particles (grass/sand/water)
- Itembox collect particle
- Wall collide particle (this is really extreme and there should
probably be others)
- Shader improvements, such as dithered shadows for alpha and reduction
of artifacts. The best way to remove all artifacts would be generating
normals for courses and using the diffuse direction as a more reliable
indication of shadowed/not.
- Fixed checkpoints not resetting on new laps.
- Fixed me not being able to count to 3. (now 3 laps instead of 4)
- Fixed battle mode courses crashing on load and during due to AI being
funny (above 31, eg 36 for block fort)
