Is your feature request related to a problem? Please describe.
Its frustrating having to set up my chat notifications the same way every single game. And many players disable trade notifications in all games anyways. I could also imagine to some people it would be useful being able to disable notifications from the beginning.

Describe the solution you'd like
The game remembers what notifications you had on/off in your last game and uses the same ones for the next game.

Describe alternatives you've considered
This could be implemented either in the client and only saved on the client or it could be stored in the backend.
It could also either be per game mode or be across all gamemodes. It could also be a setting to turn this feature off since i could imagine some players would prefer to set them up per game.

Additional context
I would happily implement this myself, seems like a good issue to get my hands dirty in the openfront code. Just need maintainer approval and direction before i go ahead. Like whether it should be client side only or not, and whether it should have a setting. Then im off to implementing it.
