[xmonad] Site name in Search prompt dialog

Hi, I made a patch that shows the name of the site in the search prompt dialog of XMonad.Actions.Search module. Now the Search Engine is changed from:

google = simpleEngine "http://www.google.com/search?num=100&q="

To the version with named engine:

google = SearchEngine "google" " http://www.google.com/search?num=100&q="

And the search dialog shows "Search [google]:" instead of "Search:" -- Luis Cabellos, "Sonrie cuando te vayas a fosilizar, Que no piensen luego que lo has pasado mal"
