* Update com_jme3_bullet_objects_PhysicsRigidBody.cpp
From docu here: http://www.bulletphysics.org/mediawiki-1.5.8/index.php/Activation_States
..
ACTIVE_TAG
Means active so that the object having the state could be moved in a step simulation. This is the "normal" state for an object to be in. Use btCollisionObject::activate() to activate an object, not btCollisionObject::setActivationState(ACTIVATE_TAG), or it may get disabled again right away, as the deactivation timer has not been reset.

* Update com_jme3_bullet_objects_PhysicsRigidBody.cpp
Settin RigidBody kinematic and then back dynamic will leave activation state to disabled causing the object never fall to sleep.
