Reworked Klingon Trefoil

A complete rework of the Trefoil, this time based upon the SVG file by http://delapouite.com/ , taken from https://game-icons.net/delapouite/originals/klingon.html .

I've removed the original ring, as it was only partial, and instead put a simple disc as background.

Both trefoil and disc are rounded off, because I think it looks nicer.

I've uploaded the "cookie" part and the trefoil separately as well, so you can add your own preferred ring.
