BGE bug #17408 fixed: Radar sensor is oriented the wrong way when the set along negative axis. Improve reliability of Radar detection by clearing the manifold cache instead of updating it.

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

BGE fix bug #17430 : BGE Collide/Touch Sensor interfearing with other unrelated sensor states. The bug was introduced in the recent logic optimization patch. It only affects collision and touch sensors. The bug is fixed by keeping track of registration count.

BGE patch: logic optimization part 2: remove inactive sensors from logic manager.
...
With this patch, only sensors that are connected to
active states are actually registered in the logic
manager. Inactive sensors won't take any CPU,
especially the Radar and Near sensors that use a
physical object for the detection: these objects
are removed from the physics engine.
To take advantage of this optimization patch, you
need to define very light idle state when the
objects are inactive: make them transparent, suspend
the physics, keep few sensors active (e,g a message
sensor to wake up), etc.

BGE bug fix (for 2.47): setParent() fix, third part: set mass to 0 when parenting. Allow loc/scale/orientation change on child object with physic controller.

BGE bug fix (good for 2.47): remove static-static collision messages on the console since previous SetParent fix. The physical object is set to static+ghost while the object is parented. This behavior will be made optional in a future release. The DisableDynamics actuator will also make the object static except that the ghost/non-ghost flag is preserved.
