Hide screensaver interface from the prefs

   patch courtesy of Wallace Wadge (thanks!).

   send() delays.

* Better fix for [12521]. Previous fix resulted in the playlist forgetting it's position if you did a play / stop / play sequence. This is the CORRECT fix.

  - sorting
  - show/hide hidden files (with '.')

 * modules/gui/ncurses.c: use <space> in the filebrowser to add the selected directory to the playlist.

* Work around the fact reading from http never returns EOF
* Dirty hack to avoid segfault on exit if we don't open at least a valid file

* Now MRLs such as ssh://user:pass@server work.

* MRLS are of the form gnomevfs://ssh://user:pass@ (if anybody has something better)
* Still some issues with some accesses (smb for instance) where it seems it required to open the directory in which the file is before opening the file itself.

* Prevent the autoplay function from playing the Shoutcast url for the xmllist. The SD modules already does this by itself. (fixes #8)
