outerHeight() fix for jQuery UI compatibility

It appears jQuery UI overloads the outerHeight() and outerWidth() methods in the latest 1.8.x versions such that with calling those functions without any params instead of the width/height the element itself is returned. See jsfiddle below:

I updated all instances of those methods to have an explicit false param instead of the null / implicit false that currently exists.
