remove take controls for movement

this is supposed to be used with AntiSlide active in the collar; instead
of pausing the collar pose when we move, we just leave the AO turned off
and use the walk defined in the AntiSlide menu of the collar

hax done by Sumi Perl on my request; we need to test it a bit more and
hopefully can make this a public release along with 3.980 collars;
relates to #263
