Revert "Fixed issue with SE_StackingCommand_Overwrite"

This reverts commit a7ce852ca5f313f0f9d89b587a35bb18be14aa4d.
Stacking issues should be resolved now

I have a feeling this could be slightly better, but it works correctly.
Bandaid fix to CopyCharacter function.
Added #showspellslist command to show us a mob's spells
Fix procing off of unattackable things

This /might/ be a little restrictive, but it should prevent easy
farming of bone chips from Boneshear etc
