Return a JSON error instead of a 404 on certain malformed URLs.
This handles the case where a route is requested, but without a required
parameter. So, /blueprints/info is requested instead of
/blueprints/info/http-server. It accomplishes this via a decorator, so
a lot of these route-related functions now have quite a few decorators
attached to them.
Typo'd URLs (/blueprints/nfo for instance) will still return a 404. I
think this is a reasonable thing to do.
