Battlebots coding evening

Everyone had a lot of fun playing code golf in November so we're continuing the theme with a round of battlebots.

Based on https://github.com/awilliams/RTanque, write an AI for a bot and then watch as they battle it out in a Gosu powered arena.

If you can't make it you can still send in a pull request to add your bot to the repo and we'll enter it for you: https://github.com/bathruby/battlebots
