Changeling personal hivemind
*Creates new living mobtype: voices who are created inside of other living mobs. They communicate only with other voices in the same mob and the mob itself.

*Uses the new mobtype for changelings. Lings now have the option to absorb the "memories" of a target. The memories can ghost on their own accord or be forced out by a changeling to prevent spam or verbal abuse. After ghosting the former voice can re-enter the original body (now probably a husk).

*Adds an argument to the ghostize verb to have the ghost refer to a new mind. This was used to have voices be able to enter their own body. - Adds the option for a living mob with voices to talk to them using ":v". (This isn't in the current patch for some reason)]

*changeling powers can now have multiple verbs tied to them
*You now talk to the voices in your head with :p for personality.
*Voices now show up in the player panel. (Note that if you make the voice into a corgi with adminmagic the poor guy will have a corgi stuck inside of him)
*Voices now again count as alive. Changed that for some reason, they should of course not hear deadchat.
