CCD collision problem

[GoogleCodeExporter]

CCD collision detection seem to ignore that collision between constraint linked 
rigid bodies might be disabled.

Reproduction: use the attached patch (CCD_collision_problem_demo.patch ) for 
GenericJointDemo to get a set up with 2 capsules: one static (the upper) and 
the other attached to it (below) such way that it can only move along the Y 
axis. Moving the nonstatic rigid body with a relatively high speed into the 
static one using the mouse results in the two capsules getting stuck together 
because of the collision. The expected behavior is that the nonstatic capsule 
should fly over the static capsule.

Rev. 2719 32 bit on a Win7 64 bit.

Suggested fix attached in a separate patch (CCD_collision_problem_fix.patch)
