OTR Proxy 0.3

This is a localhost proxy you can use with almost any AIM client in order to participate in Off-the-Record conversations. The current version is 0.3.1, which means it's still a long way from done. It still missing the following features:
- Username/password authentication to the proxy
- Having the proxy be able to use outgoing proxies itself
- Support for protocols other than AIM/ICQ
- Configurability of the proxy types and ports it uses
but it should work for most people.
