 * = About                                                                    =
 * ============================================================================
 *
 * As you all know HTML5 games don't generally need exit buttons. Neither do
 * mobile versions, as you can just Back or Home your way out. But with desktop
 * that's a whole different thing. You do want to get out without having to
 * resort to using CTRL+F4 or something similar.
 *
 * This plugin adds this option to both the title screen as well as the Game
 * End option.
 *
 * ============================================================================
 * = Usage                                                                    =
 * ============================================================================
 *
 * After you add the plugin, you can set the parameters. They're pretty much
 * self-explanatory. "Text - Exit" and "Text - To Desktop" are the text labels
 * for each respective button. The first appears in the title screen, the
 * latter in the Game End window.
 *
 * "Add to title" and "Add to Game End" both are boolean values, and determine
 * whether or not the new buttons should be added.
 *
 * On non-desktop browsers the game won't add the exit options. They could be
 * made visible, but they don't work, so it's pretty useless to keep them.
 * 
 * ============================================================================
 * = Plugin Commands                                                          =
 * ============================================================================
 *
 * This plugin contains Plugin Commands. These are as followed:
 *
 * Exit
 * ----
 * Exits the game. This can be executed for both desktop and browser-based
 * clients, but it would only work on desktop.
 *
 * ============================================================================
 * = Compatibility                                                            =

 * 
 * This plugin overwrites the functions listed below, but still uses the old
 * version, either as the basis for the function or as a fallback. It is
 * advised to place this script below other scripts that use these functions.

 * - Window_TitleCommand.prototype.makeCommandList
