Added CAP color part; Player's cap no longer uses the SHIRT color
Added METAL color as an alias of CAP color; Metal characters now uses the CAP color to tint the metal texture (was SHIRT color)
Fixed the cap inside color (was HAIR color)
Fixed the near/far warning
Added Luigi model.
Renamed all previous references to 'Luigi' to 'Mario2' since player 1
isn't always mario, and player 2 isn't always luigi.
Now server is always mario and client is always Luigi.
