use react context for current user, current server, responsive design parameters

[xImAnton]

The following contexts would be great:

• ErrorContext
  • set/get current error message
• AlertContext (from react-alert)
• UserContext
  • the current user
  • set/ get session id
• ServerContext
  • all servers
  • current server
  • server websocket
  • console messages
• ConfigContext
  • MCWeb Config
• DesignContext
  • set/get show navbar
  • get whether responsive
  • set/ get darkmode
