Balloon Yak: new Zot monster

A yak-themed chaos construction found in the realm of Zot. On death it explodes with a wind blast and a spread of chaotic clouds (based on old plague shambler code) to pressure the player to move. Spawns in rather small packs or in random single bands; the clouds would get completely over the top in typical yak band sizes. For placeholder tiles, I've recoloured the plain yak tile into red, blue, yellow and green variants; I couldn't decide which was the best balloon colour so why not use all of them (I went with red in console as it was available on "Y").
