Subject: Feature: Allow multiple users in Jabber service hook

I'd really appreciate it if you could add multi-user support to the Jabber service hook, or at the very least merge in my (bbhoss) fork of github-services that has this capability built in, documented and all.

If there is something wrong with the code, I'd love to know about it. I've sent numerous pull requests with zero response.

Also, you might want to change the password of the bot, since it was revealed in a old version of the file. Someone could easily change that password, thus denying service to everyone who uses the Jabber hook. I reported this issue to pjhyett over 7 months ago, with zero reply!
