Adds new formula: bitlbee

Adds new Bitlbee formula for version 1.2.7

    BitlBee brings IM (instant messaging) to IRC clients. It's a great
    solution for people who have an IRC client running all the time and
    don't want to run an additional MSN/AIM/whatever client.

    BitlBee currently supports the following IM networks/protocols:
    XMPP/Jabber (including Google Talk), MSN Messenger, Yahoo!
    Messenger, AIM and ICQ.
