Apply a fix already in Apache 2.0 (and add quality weights) to prevent
  us from attempting to serve .gif or any other flavor of negotiated
  resources.

  This patch fixes the Accept: header of the autoindex request so that
  it's subrequests look for text/ only, with weights applied to recover
  .html, then .txt, then some other flavor of text/* in their absense.
