The Breeze and Thunderstorms

The Breeze should have a low chance of spawning naturally outside of Trial Chambers during thunderstorms, either as a replacement for another mob (say Creepers), or as its own spawn. 

This accommodates the playstyle of certain players by allowing them access to wind charges without the need to seek out trial chambers, though in a more limited capacity. It also allows superflat players to use this new mechanic!

With the Bogged being added as a swamp variant to the Skeleton, the Breeze appearing in the howling winds of a thunderstorm is only fitting and allows a greater range of players to access it's unique mechanics.
