BETA: Added EffectRandomizeHate for switch/confusion skills. Currently the handling is quite buggy because for some reason monsters' knownlist doesnt include monsters around them o.O

In short, the effect works ok, except the part where hate can be transferred to a random mob, since MOST of the mobs dont know the mobs around them.
