Bug fix release 15-Apr-2018

[jsachs]

I have posted a new release (15-Apr-2018) in both full version and executable-only. No changes to the help file.

The changes (taken from the update log) are:

Multipoint Gradient: fixed problem with Adjust Brightness (HSV or HSL) for 48-bit color images and problem with Color number not being updated in dialog box when clicking on a control point.

Fixed bug causing random behavior when closing images if the Show Dependency button in the image browser was not depressed (this is the colored button at the top of the image browser next to the + and -).
