Bug fix release 27-Apr-2018

[jsachs]

I have posted a new release (27-Apr-2018) in full installer and executable-only. No changes to help file.

The changes (taken from the update log) are:

Fixed problem reading black and white images which have EXIF data indicating sRGB or Adobe RGB color space being assigned a color profile and then failing to open.

Fixed all sharpen transformations to set halo sliders correctly (they were still reversed when setting from a script).

Fixed bugs in many of the transformations that produce new top-level images (e.g. Stack Images, Combine Channels, Layout, etc.). They were setting the current image to an illegal value when the transformation dialog was canceled or closed.
