Add osCheckODE() function so scripts can configure for running with legacy physics engine.

  Function returns 'true' of the physics engine is configured to be 'OpenDynamicsEngine'.
  The presumption is that all other physics engines work the same (like SL) or it is a bug.
  Does not require ossl functions to be enabled.
