Lots of GLchan datatype changes.
Added GLvector4us datatype in math/m_vector.[ch] Added _math_trans_4us() in math/m_translate.[ch] Choose GLvector4ub, GLvector4us, GLvector4f at compile time based on CHAN_BITS. Made Driver.ClearColor() and Driver.ClearIndex() optional driver functions. Changed args to Driver.ClearColor(), updated drivers. Reordered files in Makefile.X11
