v1.28.0

-- Step 1 of allowing child GUIs to disable synchronized browsing through the data tree with MainGUI and providing option in the child GUIs to toggle enable/disable of synchronized browsing. This change implements array of current elements in DataTreeClass as a first step.
-- Also remove confusing Reset Group Folder menu option from MainGUI File menu and rename Rest Current Element to Reset Processing Results and also auto save the reset to groupResults on disk (the feedback from David is that this option isn't useful otherwise).
