 *   Galv's Message Busts
 * ----------------------------------------------------------------------------
 * This plugin displays a bust image from /img/pictures/ folder based on the
 * face chosen in the 'Show Text' event command.  For example:
 * If your 'Show Text' uses the 2nd face from the "Actor1" faces file, then
 * the plugin will use /img/pictures/Actor1_2.png for the bust image.
 *
 * Remember, all filenames are case sensitive, so make sure to use the correct
 * capitalization/case for your faces and busts.
 *
 * ADDED: A plugin setting called "Filename Append".
 * Whatever you put in this setting will be added to the end of the filename.
 * Using the above example, if the Filename Append setting is "_bust", then the
 * plugin will use /img/pictures/Actor1_2_bust.png instead.
 *
 * Make sure to add 'wait' between messages with different character's busts
 * for better looking transitions.
 * Use the 'Plugin' event command to change bust settings. These settings will
 * be in effect until changed, so they can be used for multiple messages. 
 *
 * NOTE: You will need to find your own bust images to use. I can not help
 * you with that. The images in the demo are for demo purposes only.
 *
 * This plugin also comes with the ability to display bust/facesets according
 * to who is in the party or a certain position from the leader's faceset.
 * This works for both the faces and busts.
 *
 * 1. Member's face.
 * Create a face file (or get from demo) called "partymember.png".
 * Number each face in this faceset from 1 to 8.
 * When this face set is used in a "Show Text" event command, it will replace
 * the face with the party member according to the face number used.
 *
 * 1. Leader's face.
 * Create a face file (or get from demo) called "partyleader.png".
 * Label your faces accordingly (for example, happy, sad, laugh. Or numbers)
 * When this face set is used in a "Show Text" event command, it will replace
 * the face with the party leader's faceset and the face number of the chosen
 * face position of the 'partyleader' faceset.
 *
 * ----------------------------------------------------------------------------
 *   PLUGIN COMMANDS (To change bust position/visibility)
 * ----------------------------------------------------------------------------
 *
 *   BUST POSITION MIRROR                    // BUST = the plugin command
 *                                           // POSITION = LEFT or RIGHT
 *                                           // MIRROR = TRUE or FALSE
 *   BUST STATUS                             // STATUS = TRUE or FALSE
 *
 * 
 * ----------------------------------------------------------------------------
 * Examples:
 * BUST LEFT FALSE    // Bust will appear on the left and not mirrored.
 * BUST RIGHT TRUE    // Bust will appear on the right, mirrored.
 * BUST FALSE         // Disable busts and use face graphics as normal.
 * ----------------------------------------------------------------------------
 *
 * ----------------------------------------------------------------------------
 *   TEXT ESCAPE CODES (During 'Show Tesxt')
 * ----------------------------------------------------------------------------
 *
 * \BST[x]            // Change the bust in the middle of a message. X is the
 *                    // number of the face without changing the face name
 *
 * \BST[x,face]       // Change the bust image to a different file name
 *
 * ----------------------------------------------------------------------------
 * Examples:
 * If a "Show Text" event command uses face number 3 from "Actor1"...
 * \BST[7]  will keep using "Actor1" face file but change the 3 to 7
 * \BST[7,Actor2]    will change the face file to "Actor2" and use face 7
