Communicator Texting for Ghosts

Ghosts can now text communicators in round, and can be texted by those back.
This is obviously logged, just in-case funny business occurs.
Adds verbs to display a log of messages that a ghost has sent and received, as well as a verb to send a message to a communicator of their choice.
