attention crazymax: fixed the race condition which caused NDS_3D_Reset and NDS_glInit to interfere with each other 

added a 5bit to 31bit conversion table covering entire range from 0 to INT_MAX to prevent such problems as alpha=31 polys being ever so slightly transparent. I applied it also to the material colors since I think those should exactly cover the whole range also.
