Four new extrude possibilities;

- Individual faces
  Keeps Mesh manifold, so removes old faces always. Also uses a
  transform based on different vectors per vertex.

- Only edges
  Just extrudes the edges (not really 'individual', the edges still
  share the vertices. Uses same transform as normal extrude for that
  reason

- Only Vertices
  Uses normal transform after extrude

Also changed code a bit, to detect whether to call a normal-based
transform after extrude, or whether to call normal grabber. For example
when you just extrude 1 edge, it uses normal grabber.

Note; extruding an entire sphere goes OK with 'individual faces'. for
other extrudes you should press 's key' when in transform. Just cannot
predict (yet) when one method has preference over another.
