Provides a nifty testing harness for services

Launch from rake using "rake test:interface" and you'll have a
handy-dandy web testing harness. Everything you need to know about a
service integration is quickly visible; you can interact with your code
right from the interface.

This makes testing things that need a pesky oauth handshake possible. If
you raise a TrepScore::ConfigurationError you'll get a page with some
output that you can use directly in the console (rake console or just
rake) to debug your issue.
