[RFA] variable window menu fix

[Martin M. Hunt]

If you open a variable window, the pulldown menu entry "Format" is enabled.  
You can then set the format although you haven't selected anything.  This 
causes an error dialog, of course.  The patch disables the pulldown menu until
something is selected.

	* library/variables.tcl (build_menu_helper): Set
	the Format menu option to "disabled" initially.
