Clear requests link

Adds a link to clear all requests. I also moved some trailing whitespace in a few places.

Addresses #5 
Without redirecting back to `?view`, like with the destroy path in the `post` route, every time you refresh the page it'll clear things out which could be unexpected behavior for the user.
Unless there's a great reason to keep it this way, could you change it to handle `clear?` with clearing the requests followed by a redirect back to `?view` ?
Thanks!
