Finished implementation of chat service interface. Test + Fixes -> Done
Basic chat (beyond spatial) is complete. Needs moderation features, and may need other tweaking, but is good for now.
Fixed a minor issue with friends. The friends list itself still does not quite work as intended, but it's better.
Added user provider methods to the chat service interface for easy use.
