Minion, Reflection and Evil Twin safety checks.

Currently you can attack other people's minions, and ETs chasing other players no matter what the safety status between you and the caster/master is. It looks like someone attempted to implement checks for ETs/reflections already but it wasn't functional. This change fixes that error and adds checks for any monster that has a master (e.g. animated mobs, future seduced mobs).

You can still attack your own minions, however we can change that also if there is enough support for it.
