P: Add "Rating is not equal to" option to the Rating filter operators

Presently one can filter images by:

"Rating is greater than or equal to"

"Rating is less than or equal to"

"Rating is equal to"

I am asking that a fourth one be added - "Rating is not equal to"

I cull my images hard and mostly keep images that hold potential as solid images for my website and possible printing.  But I will have photos that aren't great that I still want to keep for whatever reason (something unusual or funny for example) and do a quick "show" to the family.  I make those two star.  At this point, no other images have stars.  When I am about to start processing the images with potential, I don't want to see the two star images.  At present there is no way to filter them out.  A "Rating is not equal to" would fit this need perfectly.

I could see where people might also use this for one star images early in the culling process or for four or five star images near the end of the selection process, depending on how they would like their image selection workflow to be.

I believe this would be a very simple code enhancement and would be nice new capability.
