Subdivide recode assistance!

- Added subdivide sck upport for vertex groups
- Brought back subdivide-smooth, but it doesn't work as good as before yet,
  it used to catch an exception for subdividing the middle vertex of a quad,
  with edge-based subdivide it's not that simple. Will check later.
- made "number of cuts" a static variable, so it doesn't jump back to 2
  all the time

Coder level notes:

- removed the old subdivide code (yay, over 30k code less!)
- did some minor layout cleanups in the new code (just consistant syntax)
- removed redundant code parts, to enable smooth & vgroup subdiv
- subdivide smooth can do multiple cuts too, but i like to see that only
  as option when our smooth formula is good!

Compliment:

I think Johnny really made comprehensible design and nice code here. Was a
joy to work with. :)
