Block Page

[AzureMarker]

The block page was originally provided via a PHP file in the Core repo which acted as the 404 page for lighttpd. The block page is only used for IP-based blocking, which is not the default anymore (replaced by NULL).

The block page should be implemented in the API via a server-side rendered template. This is supported by Rocket via Handlebars or Tera: https://rocket.rs/v0.4/guide/responses/#templates

The block page is not a hard requirement for alpha or beta, but should be implemented by the full release so we maintain feature parity.
