[ODE] Mixing WorldStep, QuickStep and/or StepFast

[Sergey Kurdakov]

Hello all

btw regarding subject

one spare thought -  taking a look at

http://frustum.org/3d/ Engine_v0.2

thought that actually  maybe it is  possible to combine impulse based simulations etc with current approaches... at least ( not
tested much the engine at link ...)   small blocks of bricks moving under impulse approach  looked quite nice...

(I worked for some time with the guy... :) so that I have personal reasons to mention link... but anyway - this looks good)
