Add multiple configurations navigation and management

Multiple configurations  are accessed and  maintained from a  new main
window menu bar  pop up menu "Configurations". The  prior settings are
the  "Default"  entry. New  configurations  may  be added  by  cloning
existing ones.  Maintenance  and navigation is via sub  menus for each
configuration.
