Tim Mayberry 36291eb399 Make Stateful::*instant_xml methods protected and non-virtual 
Add add_instant_xml and instant_xml methods to the Session class which call
the corresponding Stateful methods with the session directory for the
directory argument

Add add_instant_xml and instant_xml methods to the Configuration class which
call the Stateful methods with ARDOUR::get_user_ardour_path() for the directory
argument
