 * Introduction
 * ============================================================================
 *
 * While RPG Maker MV Ace certainly improved the message system a whole lot, it
 * wouldn't hurt to add in a few more features, such as name windows,
 * converting textcodes to write out the icons and/or names of items, weapons,
 * armours, and* more in quicker fashion. This script also gives the developer
 * the ability to adjust the size of the message window during the game, give
 * it a separate font, and to give the player a text fast-forward feature.
 *
 * ============================================================================
 * Word Wrapping
 * ============================================================================
 *
 * Word wrapping is now possible through the message system. You can enable and
 * disable Word wrap using Plugin Commands. While using word wrap, if the word
 * is to extend past the message window's area, it will automatically go to the
 * following line. That said, word wrap will disable the editor's line breaks
 * and will require you to use the ones provided by the plugin:
 *
 * <br> or <line break> is text code to apply a line break. Use this before or
 * after a part in which you wish to start a new line.
 *
 * Keep in mind word wrapping is mostly for message windows. However, in other
 * places that you'd like to see word wrapping, such as item descriptions,
 * insert <WordWrap> at the beginning of the text to enable it.
 *
 * ============================================================================
 * Text Codes
 * ============================================================================
 *
 * By using certain text codes in your messages, you can have the game replace
 * them with the following:
 *
 * - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
 *
 * Text Code   Function
 *   \V[n]       Replaced by the value of the nth variable.
 *   \N[n]       Replaced by the name of the nth actor.
 *   \P[n]       Replaced by the name of the nth party member.
 *   \G          Replaced by the currency unit.
 *   \C[n]       Draw the subsequent text in the nth color.
 *   \I[n]       Draw the nth icon.
 *   \{          Increases the text size by one step.
 *   \}          Decreases the text size by one step.
 *   \\          Replaced with the backslash character.
 *   \$          Opens the gold window.
 *   \.          Waits 1/4th seconds.
 *   \|          Waits 1 second.
 *   \!          Waits for button input.
 *   \>          Display remaining text on same line all at once.
 *   \<          Cancel the effect that displays text all at once.
 *   \^          Do not wait for input after displaying text.

 *
 * And those are the text codes added with this script. Keep in mind that some
 * of these text codes only work for the Message Window. Otherwise, they'll
 * work for help descriptions, actor biographies, and others.
 *
 * ============================================================================
 * Plugin Commands
 * ============================================================================
 *
 * The following are some plugin commands you can use through the Event Editor
 * to change various aspects about the Message system.
 *
 * Plugin Comand
 *   MessageRows 6          = Changes the Message Rows displayed to 6. If you
 *                            are using continuous Show Text events, this will
 *                            continue displaying the following lines's texts
 *                            until it hits the row limit. Anything after that
 *                            is cut off until the next message starts to avoid
 *                            accidental overlap.
 *
 *   MessageWidth 400       = Changes the Message Window Width to 400 pixels.
 *                            This will cut off any words that are shown too
 *                            far to the right so adjust accordingly!
 *
 *   EnableWordWrap         = Enables wordwrapping. If a word extends past the
 *                            window size, it will automatically move onto the
 *                            next line. Keep in mind, you will need to use
 *                            \br to perform line breaks.
 *
 *   DisableWordWrap        = This disables wordwrapping. Line breaks will be
 *                            automatic at points where a new line is started
 *                            in the editor.
 *
 * ============================================================================
 * Changelog
 * ============================================================================
 *
 * Version 1.07:
 * - Added 'Word Wrap Space' for word wrap users. This parameter will leave a
 * space behind for those who want a space left behind.
