Stratholme - Ravaged and Broken Cadavers

* Ravaged Cadavers do not use Cadaver Worms, only Mangled Cadavers should.
* Broken Cadavers act differently. They will not use their explosion based on a timer. They will chase you down and cast it after a successful melee hit. Therefore, spell 16140 was used in vanilla and is still used nowadays. In addition, Broken Cadavers stun themselves for a short amount of time (spell 16310) to give players the opportunity to dodge the mechanic.
