Monsters and npc AI

[lordbosh]

Had a few ideas regarding NPC AI to make them more challenging in combat, and to prevent walls from being stacked and used to spawn kill them (like the eggs).

First, each monster would probably function differently based on their attack method.

Melee - Needs to recognize and charge into an enemy that deals damage to it. If using a shield, should have a shield in defensive mode to help prevent arrows and spells from hitting.

Ranged - Cast magic or shoot/throw in retaliation against an attack, even if from far away.

- Ai should also be able to target and destroy walls (and directors). In fact I'd recommend that players be able to destroy walls (and directors) as well, and they have Hp based on the level of caster.
