Add script for Tortured Druids/Sentinel in Silithus

* They will now emote and spawn a Hive'Ashi Drone on death (75% chance).
* Tortured druid also had its combat AI added. Spell IDs are correct.
Timers and threshold are guesswork (probably close to correct) based on
similar NPCs scripts.

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.
