Relax, use a couchdb backend for ejabberd.

There has been mention of using couchdb with ejabberd. Mnesia is good and so are traditional RDBMSes, but sometimes you need to relax. :) So, I started writing couchdb ejabberd modules. Authentication works and I need to do other things like roster and vcard. I just wanted to quickly announce it for people who are interested. Since I have become fond of github I have placed the code on there.
