Use a real BOSH service

My metajack.im bosh service is for testing and development only. I would suggest placing a comment in the source to that effect so that other developers know, or changing this to something else.

You're free to use the service to test this and other projects, I just don't want anyone to accidentally launch something depending on this into production. It has happened a few times already and I've had to ban those people since there is no way for me to contact them most of the time.
