Added print menu.  Grouped Save operations under a single cascading menu. Added a status message (timed) to appear in status bar when successfully saving a plot or closing the plot file.  Changed Page setup to use new device variables (margin, aspect, jx, jy).  Switched over to new Form2d proc for direct entry of window or page setup variables.
