- Make file_server_root mandatory
- Deny unused HTTP methods for endpoints
- Hide ptth_server.toml from file server
- ETag cache based on mtime

Off-project stuff:

Known issues:

Relay can't shut down gracefully if Firefox is connected to it, e.g. if Firefox
kept a connection open while watching a video.
I'm pretty sure this is a bug in Hyper, so for now I've worked around it with a
forced shutdown timer.
