Add IMeshBuffer::getColor functions

Browse Source 
Lazy access function - same as for all other members of S3DVertex (getPosition/getNormal/getTCoords).
Not sure why color was missing, maybe got added later?
Would probably be better to have a getS3DVertex function instead which would cover them all, but it's only some slow (but nice) helper function anyway.
