Battle Pong

First Godot Project to start learning game development.

Based on the tutorial by Coding with Russ.

Added mechanics:

- Hold 'Shift' for speed boost while moving the paddle.

- Press 'R' to restart the game at any time

- Press and hold 'E' to 'grab' the ball and move it around before shooting it. This allows you to "aim" it.

- Added dynamic sounds such as fade-in music, scoring points and hitting the ball with the pitch being set by the current ball speed.

- Added win condition to reach a score of 3
