Added active drawing in editmode (may need some more work), this hilightes the last selected vert/edge/face, which is needed for moving some of the UV tools into editmode.

Added copy menu for editmode for copying from the active faces material, image, UV's vcols etc,
improved on the current vertex color copy by averaging the 4th color when copying color from a tri to a quad.

And added edge crease and length copy

cerrently verts dont have a copy menu but eventually copy weights would be good.
