First public alpha version (0.8.1)

This is the first time I implement online multiplayer in a game.

This version is still in alpha because I haven't thoroughly tested it and some visual effects are missing.

Please keep in mind this was mostly a multiplayer implementation experiment. I'm using Unity's multiplayer services free tier, which comes with a relatively low capacity limit, so sometimes the game may fail to create a room due to the limit being reached. If you wait some minutes, hopefully a slot will be available to create a room once other players have finished their match.

Important notes:

• You will need to setup your 4 decks (2 for short games and 2 for long games) before you can play offline or online.
• Make sure to save all your decks by pressing the "save" button in the lower left corner of the deck setup screen.
