Log Message:
-----------
Adding GameObject setLinearVelocity(), without this interacting with objects
requires them to have logic bricks to apply force which doesn't work well when
the character is in a seperate blend file to the levels. (its also messy to
have a script & multiple motion actuators on each object you can pickup and
throw).
This is also needed for removing any force that existed before suspending
dynamics - In the case of franky hanging, resuming dynamics when he fell would
apply the velocity he had when grabbing making dropping to the ground work
unpredictably.
Also note in pydocs that enable/disable rigidbody physics doesn't work with
bullet yet.
