mod_http_errors: Add way to reuse the error page template

Browse source 
module:fire_event("http-message", {title = "hello"; message = "world"})

Goal is to enable consistent messages from Prosody. Not necessarily
error messages, but warnings or just notices.

This does cause some drift in the purpose of mod_http_errors, but that's
okay.
