AI-bot for pybridge

I've started adapting the oldlady AI by Paul Kuliniewicz (http://www.kuliniewicz.org/blog/archives/category/coding/old-lady/) as a pybridge client. So far I've made it sit at a single seat and bid, but hopefully in the next week or so it'll be fully integrated. For now it's just a glue module between the two projects, but since the original oldlady is pretty much dead, I might rewrite it closer to pybridge at some point.

There are some nice things about this AI: it's written in python, so easily compatible, and well designed. Its bidding is also fairly good. On the other hand, the play leaves something to be desired (though I have some interest in improving it). Also, the bidding logic is written in prolog, so it has some arcane dependencies, including a rather unmaintained python package (pyswip). The author has suggested rewriting it in something python-based, though this would also take some work.

Finally, there are some interface issues I need to sort out, like how to "ask" it to join or leave a table, and how to sit at multilple seats at a time.
