Better ad blocking than PithHelmet for Safari

Save userContent.css somewhere like home:Library:Safari) and then launch Safari.  Go to the Preferences... menu item, and choose the Advanced tab.  Use the stylesheet popup to choose the new userContent.css file.  And it works, without even restarting Safari. All ads gone.
