Implement proper HEAD support for static file serving.
The response should follow the same logic as the default GET behaviour (like now), but not open any file streams (because we do not need any as the response to a HEAD request cannot have any body anyway).
As a bonus, I think we need to block unsupported methods such as POST and PUT, and render the correct Allow header in response to OPTIONS.
