Fixed a few high-priority bugs that potentially prevented standard gameplay loop
- Reverted change that prevented online clients from using keyboard
- Allowed keyboard input on character customization screen for player 1
- Allowed keyboard input when pausing in-game
- Fixed join prompt not displaying in local lobby
- Steam lobbies should now only allow players to join while host is in-lobby, (i.e. not while in the middle of a game) and only allow max of 4 players
