Bug fix release 23-Jun-2019

[jsachs]

I have posted a new release (23-Jun-2019).

The changes (taken from the update log) are:

File Open: fixed problem causing switch to new file not to show up in the caption of the main image area.

Fixed problem causing the image before a splitter to be un-bypassed when the splitter is removed by closing its next-to-last branch.

Clone: added code to prevent processing a new stroke until the last one is completed.
