// Message box and visual effect system

/**

 * The ultimate message box framework for Javascript

 * Syntax is (almost) identical to the MessageBox command in NSIS

 * @param int type - a bitfield consisting of the MB_* constants

 * @param string title - the blue text at the top of the window

 * @param string text - HTML for the body of the message box

 * Properties:

 *   onclick - an array of functions to be called on button click events

 *             NOTE: key names are to be strings, and they must be the value of the input, CaSe-SeNsItIvE

 *   onbeforeclick - same as onclick but called before the messagebox div is destroyed

 * Methods:

 *   destroy: kills the running message box

 * Example:

 *   var my_message = new MessageBox(MB_OK|MB_ICONSTOP, 'Error logging in', 'The username and/or password is incorrect. Please check the username and retype your password');

 *   my_message.onclick['OK'] = function() {

 *       document.getElementById('password').value = '';

 *     };

 * Deps:

 *   Modern browser that supports DOM

 *   darken() and enlighten() (above)

 *   opacity() - required for darken() and enlighten()

 *   MB_* constants are defined in enano-lib-basic.js
