 * Jukebox plugin.
 * Allow players to add tracks to the 'jukebox' so they can play favorites
 * without waiting. Each player can only have one track in jukebox at a time.
 * Also allows to add a track from TMX, and provides related chat commands,
 * including TMX searches.
 * Finally, handles the voting and passing for chat-based votes.
 * Updated by Xymph
 *
 * Dependencies: requires plugin.rasp_votes.php, plugin.track.php, chat.records2.php;
 *               used by plugin.rasp_votes.php
