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)

* use the current copyright scheme in the about-box; removed a useless colon introduced in the last commit

only take into account "stable" releases when release_type == stable
stable and testing when == testing
stable, testing and nighlty when == nightly
all when !=
(still need a way to change release_type in the intf ... i'm lazy. default
set to "testing")

* Fixes a problem where playlist_Play was playing items that were no longer in the playlist. (Play item, playlist_Stop, remove item, add new items (enqueue), playlist_Play, and you would get the old item). This fixes it, but i think it might be a problem that actually resides deeper in the playlist core.

* Up the mms caching from 3200 ms to 5000ms. (unfortunately this is needed for a large number of streams)
