/**
 * 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
 * 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
