v1.28.3

-- Added feature to PlotProbeGUI and StimEditGUI to allow enable/disable of synchronized browsing through the data tree with MainGUI. Previously, synchronized browsing was the default. Now it is off by default and can be toggled through the Tools -> Synchronize Browsing menu. Added common generic code in DataTree to handle assigning currElem to the Guis local dataTree or to MainGUIs dataTree in accordance with the menu setting. Will Add to other GUIs as needed.
-- Change 'Data Storage Scheme' default value to 'files' in AppSettings as it is seems common for people to be working with large data sets requiring this feature to be on.
-- Minor change to setpaths to print out Homer3 version number in banner.
