anim.sl - Move out of pose using llSetAnimationOverride

This avoids any timers and trickery

Poses become a "Standing" animation override, so you don't get dragged around

There's a button to enable in Animations menu - defaults to OFF

Notes: We could add custom walks and runs etc at line number 345 (https://github.com/SumiPerl/OpenCollarUpdater/commit/beb1254ffbabbce9cffcc1d6e9c4fb88f7965964#diff-eb4caac10934d51d1502836036404d4bR345)
