Jose Diaz-Gonzalez 89196adbf1 feat: allow overriding default 404 response with custom file
This allows folks the ability to restore the previous routing functionality used by static sites backed by VueJS (as an example).

Note that all requests routed this way will respond with a '200 OK' on the server, potentially causing SEO issues.

Closes #53
