[ODE] ODE's new collision system

[Russ Smith]

ODE's new collision system has been hooked up to the rest of ODE. here's
the docs for the new API, as well as a porting guide.

  http://q12.org/ode/ode-docs.html

note that the user can activate either the old or new collision API when
ODE is compiled, by setting the ODE_OLD_COLLISION variable in
config/user-settings. BUT NOTE, even if the old ODE collision code is
used, spaces must still be created with the new API, using a parent
argument or 0.

work is continuing on adding features to the new collision code.
