[A13] Raiders never carry LMGs anymore

[Gabe1234s]

I've played quite a few A13 colonies to completion so far, some of them lasting 2-3 years, so I have fought off a lot of raids.  I have noticed that raiders will spawn with every possible weapon in the game except for LMGs.

They never carried them in a12 either, or a11 iirc.

The are currently no pawn kinds allowed to load with a LMG.

I think it's working as designed, though I'd like Tynan to confirm.

We should make sure there are enemies with LMGs where it makes sense. Mercenary gunners should be able to have them.

Fixed.
