add basic directory listing support

Current behavior when trying to browse to the basic URL is to return an error message, and then force the dev to figure out the full path to the doc and put it in. Let's present a simple directory listing instead for them to navigate if they want. This doesn't try to emulate gitiles, just produce something that isn't awful on the eyes.
