adds snake coiling (#15514)

* new signals for resting and stop pulling these are to be used as signals that will cancel the coiling * Create coiling.dm * Update coiling.dm * adds sprite accessory for coiled naga * main changes that apply the actual visuals to the coiling mechanics * adds message to coiling, fixes offset, adds action icon * coil offset was using old direction * reordering * fixes coil sprite not disappearing * fixes offsets, solves loadout issue * follows lin's suggestion and adds support for slimes by making it entirely handled in handle mutant
