Hides that annoying "sponsored by Zango" popup ad, that pops up all over the page on some sites.

Idea's taken from a greasemonkey script with the same name by PeterGriffin (http://userscripts.org/scripts/show/26862).

It's rather easy actually and the only thing I've taken from the script were IDs of elements to hide, could have done without the script, but still want to give credit to the author ;)
