Subject: [PATCH] add unique redirect for gallery links

Closes https://github.com/tom-james-watson/old-reddit-redirect/issues/60

A gallery link in the form https://www.reddit.com/gallery/qnjjvh can be
redirected to
https://old.reddit.com/r/OnePiece/comments/qnjjvh/marines_as_shinigami_by_norridzuan_art.
We only have the id to work with, but reddit will actually redirect
https://old.reddit.com/qnjjvh to the full url, so we can just redirect
to that instead.
