pkgs/back: Support listing all repos via the `/` path

This change required porting all webhandling from rocket to hyper,
because we needed fine grained control over the path the user
requested. This should also improve the memory and resources footprint
because hyper is more lower level.

I also changed all of the templates from `format!()` calls to a real
templating language because I needed to touch most code paths anyway.
