Update log:

• Shorter generated ID ! (the generated ID is now 4 digits only !) (now you can give this tiny ID to your friend to join your game).
• IP Protection ! (Now you can play online with strangers without worrying about the IP leaking issue ! (removed the IP warning message from the game)).
• Firebase database usage ! (we will use Firebase database to share the short ID online with others)(full details on how to do that in the template comments).
• Turn server usage ! (we will use a turn server to protect the IP)(full details on how to do that in the template comments).
