Style adjustment to account for longer default search scope text.  Tried to make in most cases the typeable area longer than the scope area (so hiding the scopes and just leaving the triangle at a much wider size now).  Also decreased the scope text size on very small screens so that too much text doesn't risk running off-screen.  Looked at FF and Chrome home and non-home pages so far.  Refs #153.
