Parser updates. Added the "styled" keyword to wikitables to allow them to be styled using the current theme's standard table skinning, and changes to how the image tag parser decides how to display an image (framed, inline or raw).

// 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
