refactor /storage (I.E. get files) routes and /edit/archive/:slug.

I added a new route to get files from the /archive directory but
needed to expand on the original /storage/view/:slug route so I could
seperate out the two (/storage/media and /storage/archive)
directories.

I added a check to make sure the archive entry
requested (/edit/archive/:slug) exists and return a 404 if it doesn't.
