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.

Adds critter crates

Fixed several conflicts present in last pull request, should be fine
now.

All animals ordered through cargo will arrive in critter crates. These
crates are designed for the safe transport of animals. Critter crates
can only be unlocked from the outside and automatically lock when
closed. You can resist your way out of the crates. Critter crates are
counted as normal crates when sent back to CentComm.

Adds cat crate (cost: 40 points).

Corgi crate now has a 50-50% chance of either containing a male or
female corgi.
Moves critter crate sprites from storage.dmi to closet.dmi.

Removes redundant large animal crates.
Pugs uncommented in supplypacks

Adds the replica syndicate space helmet to the list of prizes able to be obtained from the arcade machine.
Made it so instead of getting the suit or a helmet, you will receive both inside a box that looks very similar to the one you get for ordering a real suit from an uplink.
Fixed a typo in the box's description, thanks Kaze.
