Version 0.21.3

Hello everyone - I'm back from my vacation, so now work on abstractanks continues. Here's another bugfix release. This one fixes all known important multiplayer bugs!

• Fixed problem connecting to LAN servers when the server was published online
• Server list is now polled asynchronously, which make the menu transition smoother
• Fixed multiple update problems in the multiplayer UI
• Mac version now uses folder-based installation, as recommended by itch
• Supporting unicode characters (e.g. umlauts) for multiplayer chat
• Fixed client not getting notified of server disconnect

In other news, I just set up an official discord channel:

Come join us to find other players or just talk about the game and give me feedback.
