Make the differing mods warning only appear for mods that are not on the whitelist

[slender mica]

This would mean checking your opponent's mods is something you don't need to do every single time

maybe add a secondary warning that appears when one player has order enabled and the other doesn't

[twilit violet]

The second point is being implemented

[slender mica]

maybe add a third warning if either player doesn't have a fully unlocked profile

[crimson nexus]

This already exists
