recent CVS changes...

Fixed .pls file support.  Pretty names (embedded within the .pls file) are
now displayed on the SliMP3 display and web access for the first item
in the .pls file, as before.  For the purposes of playing and navigation,
.pls files are treated as a song.

Fixed a bug where the record button didn't work for individual songs anymore.

Fixed a bug where the right button didn't work for M3U playlist items.

Added --httpport to the command line interface and usage information.

Made directory display show the item number within a directory as well as the total count.  As in:

-------------------------------
Blues (8 of 17)
John Lee Hooker
-------------------------------

Removed extraneous debugging messages.
Fixed a couple of potentially crashing bugs.
Improved pause/play/repeating.
Added a little bit of remote control documentation.

--------------------------------------------------------------------------
Feels pretty stable to me.  Pound on it guys...
