Bug fix release 2.5-Sep-2018

[jsachs]

I have posted a new release (2.5-Sep-2018) in full installer and executable-only versions. Minor changes to help file.

The changes (taken from the update log) are:

Mask: modified Undo for Rectangle, Oval, Polygon, Spline, and Gradient mask tools to let you edit the locations of control points and re-apply the tool. When you click Undo after an Apply for these mask tools, instead of undoing the entire operation in one step, it happens in two steps. The first Undo reverses the Apply and the second Undo reverses the mask operation.

Thanks for this function. I really like it.
