Two more wavk bugs (help he's pestering me!)

- 1702; edge selection should be evaluated properly before adding face
- 1704; crash in separate, two causes here:
        - separate didnt make selection flags consistant (needed badly
          there because of evil code)
        - after adding quad (Fkey) the face was not selected, but its
          vertices were... that can give bad bad crashes
