Headshot Multiplier option on Custom Weapons (Entity Prefabs)

Very essential functionality of any weapon that’s been completely missing from the weapon templates for some strange reason, would be very nice to have this so we could better fine-tune our items.

By extension it would also be incredibly helpful to have a Damage Cap setting for the Shotgun template, as many Epic-made Shotguns have such thing, on top of there already being an option to change it for existing weapons in the Damage Amplifier Powerup Device.
