Version 1.3. released

Thanks for the help with testing v1.3! As of now ChessVR supports the oculus rift as well with a gamepad as well as some achievments! But there are a few things more as well. Check it out and let me know what you think! Changelog: ADDED: UCI support, comes by default with stockfish but you can replace that (if your prefered engine doesn't seem to work tell me which one and I'll look into it). ADDED: Challenges, try yourself at some chess puzzles (All of them require you to win in 2 moves) ADDED: Gamepad support ADDED: Steam achievements ADDED: Free movement, if you don't like the default position you can change that now (touchpad on vive controller, wasd eq, right stick/rb/lb on gamepad) ADDED: Turn indicator, the players base lights up ADDED: Speed up animation if you don't want to wait for the whole animation (grip button/spacebar/"X" on gamepad) FIXED: Corrected white/black selection FIXED: Bishop/Queen animation
