ooops -- hopefully I've included all the files this time (must've been getting
dangerously close to the end of the week when I posted that one) plus I've
cleaned up the action a bit so it won't display unless there are saved
searches. Also it now supports clearing individual searches as well as clearing
them all in one go.

this uses the 'delete.gif' icon which isn't in Whups yet - so if this looks ok
feel free to copy it over.
