Moved around functions from url.js to separate helper file
Changed the error handling and made som syntactic choices to make it more
readable
Changed error handling in app and removed some comments in url

Error handling is now done not by looking for a view to render, but piping down
an object. This is probably not going to be good long term, but it's cleaner
than the message that express generates.
