Here's the best attempt for the high pass filter. Will edit the summary later when the middle gray issue is solved as I have no idea how to fix that.

Implements basic version of high pass filter for Krita. More versions may or may not to come to Krita from GIMP versions. However, I decided not to do grayscale version as Krita already have de-saturation filter which takes care of that part nicely.
