Bot should do json rpc over sockets for extensions.

[aarondl]

The extension package needs writing.

In this extension there should be a way for a process to start as an extension. That means to hook into an existing bot via config file or hardcoded config or what have you. This probably means extra configuration options for the bot, and a special configuration for the extension itself.

Special note for the data and config packages, how do we provide extensions with access to these? How do we allow extensions to communicate with each other? Do we provide services for the extensions such as whois lookup, and storage? All these things should be considered while building this package.
