Remove our aliasing of OpenLayers.Util.getElement to window.$.
Fix up a test that used our $().
Fix the examples that used our '$' method.
No need to mockup a custom $-method in test anymore.
Be consistent when aliasing OpenLayers.Util.getElement in examples.
Patch from http://trac.osgeo.org/openlayers/ticket/3307.

Uses a remote GeoServer now, which is added to the allowed hosts for proxy.cgi.
