Subject: [PATCH] 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.
