Continuing to work on the Multiplayer implementaion

A tiny progress update on the multiplayer

• The multiplayer is now functional but still requires work. Powerups as an example don't fully work on the Network yet and the AI needs to be brought over to the multiplayer environment 
• Lobbies, the round logic and finishing the game works fine on a networked game. 

I will soon upload a Testversion for you to try out. For now it's still a tiny bit to early though.
