Title: Add backtrace to development routing error page

If a user gets a routing error due to a view helper such as using user_path without an :id they must go to their logs to see the backtrace. By adding in the trace template, a user can see which line the error occurred on without leaving the browser.

When a routing error occurs outside of the view the application trace will be blank and will not confuse developers.
