Log Message:
-----------
BGE bug #17409 fixed: BGE Near Sensor Incorrect once inside the radius. The bug
is located in Bullet: the manifold contact points for non-response objects
(sensor, ghost) are not refreshed and stay in the cash as long as the objects
overlap in the broad phase. Instead of fixing Bullet, I put a work around in
the BGE. This may need review when a new Bullet library is integrated
