Add a chance for traitor surplus crates to be/contain nukie class crates

[Flaborized]

I think getting something so geared towards rampaging and so structured would be bad even though it'd be sort of funny. I also think it would make nukeops less unique. As it stands, a lot of the operative's stuff is exclusive to nukeops. By giving them to traitors rarely in a very commonly bought traitor item you'd see it more often and it'd lose some the unique nukeop-only charm it has. Being able to fake being an operative is funny but one of the things I like the most about the new operative suits is that you can't fake them like the old redsuits. Seeing even just one person in operative gear totally confirms operatives and therefore it's an intense specific feeling that I think would be messed up if traitors could get the same stuff.

I also think that one of the strong parts of surplus crates is how they give you always randomized sets of gear. It's one of those "you never see the same thing twice" sorts of things right now. There's also a great deal of room for doing things how you like with the crates currently because rarely do you get a specific set of items that are designed around one specific gimmick or point you so directly into doing something, so it encourages players to improvise with what they have in unique ways. While it's certainly possible to run a gimmick with nukeops gear, it doesn't push you into coming up with ways to use what you have in the same way standard crates do.
