display_playlists: balance parentheses in a comment
display_playlists: remove outdated debugging printfs
playlist_display: support dropping playlist into an itdb
playlist_display: remove a comment about "SPL data"

I wasn't able to find any information about what that is.
playlist_display: reduce duplicate code
main: add \n after "Error parsing options: %s"
main: translate "Error parsing options: %s\n"
libgtkpod/prefs: add --playcount option

This option will have to be implemented, because glib requires each
option to have a long form. The purpose of this patch is to make its
introduction visible in the changelog.
use g_option_* for gtkpod's own options, too

It's already used for the options of other libraries (gtk and
brasero).

The options are handled in a delayed fashion: Parsing is done
at the same time as all other command line parsing, but the
results are handled at the same time as they were before.
Media player fixes

* Return status message if a track is not played for whatever reason

* Ensure the buttons are stopped if the track cannot be played

* Reset the track index when a new set of tracks are selected, otherwise
  the index can be larger than the total number of selected tracks!
