Add support for titan:// to the gemini server

Titan is a gemini add-on protocol so it really didn't make sense to
build it out in a separate package. The most significant difference in
titan for the purposes of implementation here is that requests can have
bodies following the URL line.

Since gus.Request is a struct, the only way to smuggle in the new field
(a reader for the body) was to stash it in the context.
