dont use tface hide or select anymore, since maintaining 2 sets of hide/select data for each face is annoying.

using mface->flag for both.

Also found that the cdDM_drawMappedFaces and cdDM_drawFacesTex_common could get normals mixed up when rendering hidden faces. because hidden/invisible faces used continue without advancing to the next normal.
