Remove a superfluous FS request for the MD5 checksum of every added file sent through mod_dav_svn's update editor.  As it turns out, the editor wasn't doing anything with the value, and the driver of the editor (the reporter logic) provides exactly that same checksum via the editor's close_file() interface anyway.

  (item_baton_t): Remove now-used 'text_checksum' member.
  (add_helper): Don't bother calculating the checksum -- we never used
    the results of this calculation anyway!
  (close_helper): Don't transmit the text checksum -- upd_close_file()
    does this itself now.
  (upd_close_file): Transmit 'text_checksum' directly.
