Remove Clear Website Data from preferences dialog
Currently you need to visit the Privacy panel in Preferences to view and clear website data. But website data are not preferences, so this really doesn't make sense. Let's remove it from the preferences dialog and just have a separate dialog. We could group it with Firefox Sync and Import and Export in the window menu, since all of these relate to data management.
