Initial commit

double precision fix
stop character move iteration if successfully moved to target position
Add Move() for characters ( do a precise single shot move/displacement ) + fix for nomotion check
fix compile error
throw spheres in demos (with ; button)

When disabled then kinematic character will stop moving,gravity,collision detection etc and basically become a kinematic object
Accumulate Move() displacement request in btKinematicCharacterController
