 * Support for the flowplayer 3.x.x flash video player. Now incorporates the former separate flowplayer3_playlist plugin.
 * NOTE: Flash players do not support external albums!
 *
 * Note on splash images: Flowplayer will try to use the first frame of a movie as a splash image or a videothumb if existing.
 *
 * The playlist part of the plugin supports custom CSS styling. You may override the default by placing a CSS file your theme folder:
 * flowplayer3_playlist.css or alternativels within the user plugins folder /flowplayer3/flowplayer3_playlist.css
 * This will allow you to customize the appearance of the comments on your site.

/**
 * Show the content of an media album with .flv/.mp4/.mp3 movie/audio files only as a playlist or as separate players with Flowplayer 3
 * Important: The Flowplayer 3 plugin needs to be activated to use this plugin. This plugin shares all settings with this plugin, too.
 *
 * You can either show a 'one player window' playlist or show all items as separate players paginated. See the examples below.
 * (set in the settings for thumbs per page) on one page (like on a audio or podcast blog).
 *
 * There are two usage modes:
 *
 * a) 'playlist'
 * The playlist is meant to replace the 'next_image()' loop on a theme's album.php.
 * It can be used with a special 'album theme' that can be assigned to media albums with with .flv/.mp4/.mp3s, although Flowplayer 3 also supports images
 * Replace the entire 'next_image()' loop on album.php with this:
 * <?php flowplayerPlaylist("playlist"); ?>
 *
 * This produces the following html:
 * <div class="wrapper">
 * <a class="up" title="Up"></a>
 * <div class="playlist">
 * <div class="clips">
 * <!-- single playlist entry as an "template" -->
 * <a href="${url}">${title}</a>
 * </div>
 * </div>
 * <a class="down" title="Down"></a>
 * </div>
 * </div>
 * This is styled by the css file 'playlist.css" that is located within the 'zp-core/plugins/flowplayer3_playlist/flowplayer3_playlist.css' by default.
 * Alternatively you can style it specifically for your theme. Just place a css file named "flowplayer3_playlist.css" in your theme's folder.
 *
 * b) 'players'
 * This displays each audio/movie file as a separate player on album.php.
 * If there is no videothumb image for an mp3 file existing only the player control bar is shown.
 * Modify the 'next_image()' loop on album.php like this:
 * <?php
 * while (next_image()):
 * flowplayerPlaylist("players");
 * endwhile;
 * ?>
 * Of course you can add further functions to b) like printImageTitle() etc., too.
 *
 * @param string $option The mode to use "players", "playlist" or "playlist-mp3". "playlist-mp3" is the same as "playlist" except that only the controlbar is shown (if you are too lazy for custom video thumbs and don't like the empty screen)
 * @param string $albumfolder For "playlist" mode only: To show a playlist of an specific album directly on another page (for example on index.php). Note: Currently it is not possible to have several playlists on one page
