[Social] Some early testing doing openid against ejabberd

[anders conbere]

you can play with it at

http://conbere.org:5280/openid/auth/

I'm still figuring out how to write ejabberd modules so it's really
rough around the edges, but basically if you put in the credentials
for a valid user ejabberd will spit back a little message that says
"Authed: true" or "Authed: false"

you can see a user that passes the test with

username: tester
password: password

I'll be working on enabling the whole openid workflow eventually but
for now I'm just pleased that I got that much working.
