Tweak RM2 Warmup

[GrahammerTek]

Changes

• Change the RM2's warmup time to that of SMG/shotgun type weapons.

Reasoning

• Flamethrowers in CE are close-ranged spray and pray weapons, similar to a shotgun or SMG, yet they use the warm up times of full-sized rifles. This caused many situations where pawns won't fire until the target is basically inside the minimum firing range circle and getting dangerously close to the shooter.

Alternatives

• "Hold still while I aim this flamethrower"

Testing
