Title: Scripts/Spells: added Interrupt effect for Maim/Bash/Hammer of Justice

As per dbc description, those three spells all have:
Description: Stuns the target for $d and interrupts non-player spellcasting for $32747d
Spell 32747 was not linked to them and need a small script to be applied only to creatures.
