New genre: Autobattler

This is a request that I never anticipated I'd be making, but Dota Auto Chess happened and here we are! For the ever-growing list of autobattler games, we've had to list the strategy and trivia/board game genres, which isn't terribly ideal. As was necessary when MOBA was on the rise, I believe it's time that we add autobattler as a selectable genre for these games.

I have tried many times in the past to get new genres added to no luck. I would suggest this be a concept instead as it certainly deserves a page.
