Synthesize and host vlc-x-callback stream links

Tired of using the 'open network stream' UI in VLC for iOS to view
large videos hosted elsewhere on your LAN? Me too. Here's the medicine.

The idea is that iOS clients should use a separate route distinct from the
video file URIs (e.g. /vlc/, if the files are in /vids/) to get the
synthesized vlc-x-callbacks, and all requests outside that route
are served as vanila twisted.web.static.File() resources

We'll build a single html page that recursively lists all files under
VIDEO_ROOT that have an extension in the valid_extensions array (so...
if your VIDEO_ROOT is super huge, this might be a bad idea)
