Added Support For AZERTY Keyboards!

Added an optional control scheme for users with AZERTY keyboards! 

• Arrow keys can now be used to move (instead of WASD), and the SPACEBAR can now be used to shoot (instead of LEFT CLICK) for a more comfortable user experience for those using the arrow keys. 

• Also updated the CONTROLS section of the game's page to reflect this update.

Thanks for reading, and I hope a lot more people can enjoy the game now. :)
