Improvements to game controls, performance and bot spawning — To The Death Steam update #1376720

Player control change Player can now stand still and aim if they are only pushing the aim stick and not the move stick (previously it was hard to aim without the character also moving slightly), but if both sticks are being used this results in a combined aim and movement in which the aim stick contributes to movement speed as well as controlling aim. Sounds complicated, but give it a try. It keeps the nice movement from before but allows better aiming too. Feels better than before. Bot Spawning significantly improved Previously each bot spawner would spawn it's bots at one, predefined / invisible, location that never changed. Now each spawner has three points at which it can spawn a bot. These three points are clearly marked by spawn pads, which are evenly distributed around the arena. Bots will usually spawn at the pad which the player is closest to. This makes the gameplay much harder...
