* when setting the face, images with alpha's will set the texface's alpha option.
* added a draw even to redraw view3d and uv/image view - so the Draw Faces button redraws properly.
* made a macro for checking if the object will draw with textures
* textured meshes in editmode only draw a selected face overlay (otherwise the entire mesh would get a plue tint wich isnt
nice for viewing textures), the selected highlight is still there, this is how Face/UV mode looked.
* Alpha clipping STILL had a case where it wasnt disabled and the interface had its alpha clipped, this should be fixed now.
