+Prototype replaces document.getElementsByClassName with it's own version. However many browsers
+now come with their own implementation, and prototype's is much slower.
+
+This fixes this by restoring the original after prototype is loaded.
+
+@todo: Safari 3 used to come with a broken document.getElementsByClassName. We should use
+the same checks jQuery does and not restore the function if it doesn't work the same as the spec.
