Support for /aclk link referer

Hi, i'm using ur script to get the search keywords, but trying to get it from traffic from payed links, there is no result. Watching the url i can see that the keywords are at the end of the url.

I know this is about 5 years too late. However, this should now work in the latest version of the class.
