[Feature request] Add prefab lists for Fire Effects modules (like Muzzle Flashes)

[Cheo]

Hello, the Muzzle, Smoke and Shell Effect fire effects modules each only contain a single slot for their spawned prefab. We should have a list available instead, with one being randomly chosen to create some variety instead of always having the same effects. We can easily add this ourselves but this is something that should be implemented out of the box. Thanks in advance.
