Suppress the "... - nothing changed" status banner presented when a form is submitted. This is triggered only when only quiet properties are changed. See: https://sourceforge.net/p/roundup/mailman/roundup-users/thread/20170421012107.E040180690%40vm71.cs.umb.edu/ with subject: [Roundup-users] Does anybody think feedback saying "nothing changed" is useful?
