* 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()
