Added custom vertex data support to editmode. Only used for vertex groups

now, others can be added later (sticky, shape keys). Beside one small fix
for knife exact vertex group interpolation, is intended to work the same
as before.

Also fixes bug #5200, related to editmode undo and vertex groups. And
corrects the editmode to faceselect mode selection conversion, that was
broken in a previous commit.
