Fixes for Beta issues implemented

Hello everyone,

Here's a quick update of the changes implemented so far this week:

• Game now shows the actual chat key mapping next to the chat icon.
  You can change the key mapping in the main menu. It is highly recommended to use Enter, as the chosen key is also used to submit messages in the chat. I.e. if the chosen key for chat was "z", messages in chat must also be submitted using "z".
  
  
• Active players will now see alerts before the server will be shut-down for maintenance.
  There will be three alerts: 15 minutes, 5 minutes and final alert. The server will shut down immediately after the final warning, so make sure to save any of your progress before then.
  
  
• A fix was implemented for (Wacom) tablets not working in the game on Windows computers.
  You may have to activate "Windows Ink" for the stylus to work properly in the game.
  
  Thank you for your patience as we continue to work on the issues reported via our ticket system!
