- removed USE_CCGSUBSURF define (always on now)

 - added G.editMesh->derived pointer... idea is to use this
   for mesh derived from editmesh instead of Mesh->derived (as the
   derived mesh tends to vary depending on what it came from).

   This part could be cleaner, also there may problems with it not
   being invalidated correctly.

 - And most importantly: In case people were beginning to worry all
   these edits were just crazy zr stuff, the big point comes about:
   Incremental subsurf calculation is now enabled. This gives massive
   speed improvements when editing a large mesh.

   For the eye-candy happy: try setting G.rt==52 before entering editmode
   and the edges and vertices (in optimal mode) will switch to displaying
   visually the age since a region has last been calculated. Lots of
   fun!
