Subject: [PATCH] Add playlist wrappers for lua

adds wrappers for the functions playlist_sync, playlist_remove_all_tracks, and playlist_insert_track, playlist_insert_directory
playlist_{sync,remove_all_tracks} take no arguments
playlist_insert_{track,directory} only have one required argument (either the filename or directory name)
They take as optional arguments position, queue, and either sync or recurse

They all just pass NULL to work with the current playlist

also adds constants for:
PLAYLIST_PREPEND,
PLAYLIST_INSERT,
PLAYLIST_INSERT_LAST,
PLAYLIST_INSERT_FIRST,
PLAYLIST_INSERT_SHUFFLED,
PLAYLIST_REPLACE, and
PLAYLIST_INSERT_LAST_SHUFFLED
