v1.11.3

-- Add menuItemChangeGroup and menuItemSaveGroup menu options to all GUIs to be able to change group (to load derived data from groupResults.mat) and save group (to save derived data to groupResults.mat) same way in all the GUIs when running standalone. When not running standalone hide those menu options to keep things coherent (so that user doesn't change group in stimGUI while Homer3 still has the old data set loaded).
-- Fix a bug when closing Homer3 when ProcStreamOptionsGUI is also open.
-- Fix small bug in procStreamGUI when close this GUI.
