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.
