Subject: BulletSim: remove time scaling of computed vehicle absolute velocity
 since Bullet will scale the movement by the time slice. Restore
 LIMIT_MOTOR_UP to definitition of BOAT simce some vehicle engines use it even
 for land vehicles. Push vehicle parameter updates through the regular
 property update to solve vehicles floating off when they should be stopped.
