[MIRROR] Windows "lag" fix (#2093)

* Windows "lag" fix (#55372)

Change to Move() to make only anchored windows to update the air when they move through the turfs (should prevent abusable situations of lag machines too)
Makes singulo from stage 2 unanchor windows when pulling them (low performance increment for singulo(?))
Why It's Good For The Game

less abusable lag good
Changelog

cl
tweak: only anchored windows call move_update_turf()
tweak: singularities from stage 2 and over will unanchor windows
/cl
