Resolve issue with specs and the ordering of the plugins
First rewrite of using hooks properly
Refactor so that the applications environment variable is passed into our hooks
Stupid whitespaces
Refactor existing plugins so that they use the new block structure
No longer need method_missing call
More whitespace love. My settings seem to be acting up
Refactored to make plugins play nicer. Still needs some revision as it
is now harder to work out whether a plugin has been successfully loaded
or not
Refactoring specs
Update README
Extract method from within Rack::Tracker::Plugins#add_plugins
