Christmas 2020 Coop

I was about to mention this, since we would only update this config until the event finishes.

I have no idea how long the list should be. We have 22 missions, so we can make the list on the 24th shorter and remove the ones we played on/ add more as the days go...

Not necessary, but maybe as Maki said, we can exhaust all versions of snowy missions we have. So we will have Arctic 3 and 4, Arctic 1 Extended, Arctic 4 Radiocamp, Alps 1 Fatal Airdrop, Alps 1... etc not in the same list, just to be updated on the main list. We will need to add usual favorite missions like Brest, Africa 3 Oasis etc...

I guess we will have to pick them ourselves at some point.
