Cupid bootswatch

Bootswatch which was available for a limited time around 14th Feb this year. A bit silly and there are a couple of issues with some styles (left admin menu block links and headers). I'm unsure whether you'd want to merge this but noticed you had Shamrock and figured it might be a bit of fun too. Made me chuckle and interesting to see what you can do with bootswatches. Using `--vars-only` it's actually looks kind of okay if not a bit garish.
