- MBall displays smooth again in 3d win (coding nice smooth for curves

borkened this... )

- Improved rule for adding face (FKEY); it now checks first for existance
  of 4 connected edges, if that exists a face is created anyway, otherwise
  it does the convex test. Alexander correctly noted that for subsurfs
  non-convex quads should be allowed anyway. Hope this rule satisfies it.
