[dev1026] Changes to Claiming and Engaging Enemies

[Zenaku]

I think this could work well if it comes with a /blockaid type command. Not being able to toggle this mechanic on/off would really kinda suck..

it seem like there no /blockaid but then again for NM/HNM there is a /blockaid no one can cure from outside the party. So maybe it only works for mobs outside in the open.
