Dump wheel collider info.
Bring in my config node parser.

Man, that script.py gets around :P Anyway, this will be used by the wheel
utility I'm working on, and eventually in the IVA support tools I want to
create. Still need to implement config node creation/writing.
Get config node writing working.
Initial work on creating a wheel settings tool.

Right now, it just dumps a config node for any wheel colliders found in the
part.
