Reviewed by Geoff Garen. Let Frame hold a RefPtr<Settings> so Frame::settings() isn't forced to go through Page. It now also returns a reference, as it can never be null. Removed 8.8 million lines of null-checking as a result. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@154219 268f45cc-cd09-0410-ab3c-d52691b4dbfc
