[ODE] Auto-Disabling?

I'm forgetting that also -- currently I don't use ODE at all :)

Ok. My last "patch" did have separate linear/angular tresholds. All
auto-disable params where in world, AND in bodies. Bodies get world
params by default, but can be changed on a per-body case (there also
existed a helper function to transfer params from world to body). Of
course, that broke the documented StepFast API...

So, if I make this:
* all auto-disable stuff is conditional via #define in config.
* auto-disable params are like written above (default ones in world,
also per-body params), with separate linear and angular tresholds.
* auto-disable time is controlled with "time" AND "steps", both must be
satisfied for a body to be disabled.
Would that be ok?
