for bug #168411, we changed the nsIBookmarksService interface, but we forgot change the uuid. for the branch, we are backing out the change to the interface as we don't want the interface to change on the branch. sr=bryner git-svn-id: svn://10.0.0.236/trunk@200696 18797224-902f-48f8-a5cc-f745e15eee43
