twisted.web.static's file listing should decode filenames properly

twisted.web's static file listing should be using sys.getfilesystemencoding() to figure out how to decode filenames, instead of assuming the filenames are already in the appropriate outbound encoding

Actually, it seems that it's not even setting an outbound encoding, and letting the browser's default kick in, which on my firefox is iso-8859-1. So it should not just decode from the filesystem, it should also encode to a particular encoding (almost certainly utf-8) and specify that encoding in the headers it writes.

Start by reading twisted.web.static's file-listing implementation and how it currently constructs response headers. Verify behavior with filenames using non-ASCII filesystem encodings; done means filenames are decoded using the filesystem encoding, encoded as UTF-8 for the response, and the response declares that encoding.
