[Goonchat] Pause button

Created by: N3X15

Executive Summary

Goonchat can be completely paused by clicking on a pause button, which redirects incoming chat to a background queue. When resumed by clicking the play button, the queue is dumped to the chat window and it resumes. All of this is done in Javascript on the client.

Also adds a highly half-assed debugging flag for running goonchat outside of BYOND.
