Subject: Applied patch from mantis #3820 which changed the clearing of the
 ScenePresence.m_forcesList, so it used the List.Clear method rather than
 doing a loop through the list and manually removing each item. Thanks dslake.
 I also fixed the issue where the code also loops through the m_forcesList and
 copies each force to the ScenePresence's movementVector. Which resulted in
 only the last force in the list actually be acted on. As each copy overrode
 the last one. So now it only copies the last force in the list.
