Adds a link to look for current Magic The Gathering card in http://www.magicspoiler.com/

You can search Magic The Gathering cards in scryfall.com. There's some useful links there, but what I found to miss the most was a direct link to magicspoiler.com where there's a comment section below the card. Anyway, this script adds a link to the card in magicspoiler.com page. Not 100% tested.
Button goes to top of TOOLBOX column in bottom left, see screenshot.
