Remove screen_setup method

This change removes the 'screen_setup' method.  This method was called with a 'try' from the ProMotion gem.  screen_setup did a send to a 'get_title' method, which then failed.  I don't think the 'get_title' method exists (at least I could not find it.)  I could not find any other usages for 'screen_setup'.  Please review and advise.

Thanks!
