Build a bot to play the game

Build a bot in a separate module that plays the game. It'll have to:

- Get the location of the food and the snake
- Find the best path to follow between those two points
- Make the path it's currently following visible with lines
- The path finding should prioritize not getting the snake stuck in a circle with it's own body around, not just the closest path
- Change the snake's direction on each step to follow the determined path
- Get the game to run faster when the bot is playing

This could also be made with an AI later on.
