add eclipse workspace files to .gitignore
Adjustments to queue_move/queue_remove, mostly for consistency
Keep automake happy and warning free with subdir-objects
Fix "play next" command - the queue was not circular anymore due the
missing setting of pl_prev of the next song and start the shuffle-queue
with ps_shuffle
Merge pull request #24 from chme/fixaddnextforshuffle

Fix queue_add_next command
Make sure albums/artists appear the same despite different capitalization
Remove unused variable in queue_next_add
Added support for playqueue-contents with negativ span value (returns the previously played songs)
fixes for playqueue-contents
fixup indentation
Remove dead code: playback_next_bh and playback_prev_bh are only called
during playback_pause. In playback_pause "cur_playing" is always set to
NULL so that in playback_next_bh and playback_prev_bh only the
else-clause can become true.
