Api: Admin communication system

[daleighan]

This will be a part on user profiles that allows for the tracking of e-mail and text communications. It should also allow the resending of communications. There will also be a web branch for this.
What it will need:

1. A new user_coms table
2. Store all outgoing texts/emails in this table
3. An interface that shows the history of emails sent out to a user and allows sending them again. It may eventually have various ways of sorting users
4. An interface that shows a text messaging thread with the user
