Google link converter

Links provided in the search results of Google look something like

http://www.google.co.uk/url?sa=t&source=web&cd=1&ved=0A&url=http%3A%2F%2Fabc.go.com%2F&rct=j&q=abc&ei=kuw&cad=rja

when the URL it links to is simply

http://abc.go.com/

This tool allows users to transform the former into the later for easier copying and pasting.
