Title: Quick patch to enable $server->default_index('/index.html');

This enabled a default static file from the document_root and
resolves http://[::1]:8080/ to http://[::1]:8080/index.html (rather than the unhelpful blank page.)

(This is just an outline, I'm sure you will want to do it more cleanly than this dirty hack.)
