v0.1 Changelogs

Added the following feature for the first development release:

- One-player mode: move with arrow keys to get food and grow.

- Two-player mode: P1 moves with arrow keys, P2 moves with WASD

- Custom Level mode: Currently insecure, so only can randomly generate levels for the user to play. Later I will add a way for users to make their own levels with a text editor.

- Main Menu: Used to access different modes (very bad, will improve one day)
