/**
 * Enhance Forms with JS widget stuff
 *
 * Some fixes:
 * - 24 instead of 12 for dateTime()
 * - postLink() has class postLink, deleteLink() class deleteLink
 * - normalize for textareas
 * - novalidate can be applied globally via Configure
 *
 * Improvements:
 * - deleteLink() available
 * - datalist
 * - datetime picker added automatically
 *
 * NEW:
 * - Buffer your scripts with js=>inline, but remember to use
 *   $this->Js->writeBuffer() with onDomReady=>false then, though.

	 * - `error` - control the error message that is produced
	 * - `empty` - String or boolean to enable empty select box options.
	 * - `before` - Content to place before the label + input.

	 * - `format` - format template for element order. Any element that is not in the array, will not be in the output.
