 * [ 0.2 ] Original by Jonathan Howard

 *         <charles@doublerebel.com>
 *
 * jQuery Pause
 * version 0.3
 *
 * Requires: jQuery 1.2 (I think that's when jQuery updated the queue method)
 *
 * Feel free to do whatever you'd like with this, just please give credit where
 * credit is due.
 *
 *
 *
 * pause() will hold everything in the queue for a given number of milliseconds,
 * or 1000 milliseconds if none is given.
 *
 *
 *
 * unpause() will clear the queue of everything of a given type, or 'fx' if no
 * type is given.
