Condition Module Refactor

See comment below...

The condition module was a hack from the start. It never should have lived as a module on Perry::Base. This should also be moved to a middleware. Some of the method_missing stuff may need to be implemented as a mix-in on Perry::Base. There may be some stuff we need to do to safely allow middleware to duck punch functionality into Perry.

So, after taking a closer look, this isn't going to be possible. I still would like to strip the Conditions module out and either host it as a separate gem or just throw it out.
