v0.3: Multiple Rounds, Scoreboard, Lobby

Added features:

• After a completed round, a Scoreboard is shown.
• The host has the opportunity to start another round.
• Replaced the ugly default Network Lobby with a nice looking, mobile friendly one

Notes:

• The winners and points for a Stich are still chosen randomly, thus the game is still quite pointless.
• Enabled debug mode in the build to make errors easier to spot.

Installation:

• Windows: download and run the setup file
• Android: download and install the apk file
