The Great Fire Extinguisher Refactor

[Fordoxia]

What Does This PR Do

Migrates fire extinguishers, firefighter backpack tanks, and the atmos MODsuit firefighter module to the new attack chain.

Refactors the above - modsuit module especially is now a subtype of the backpack module.

Atmos backpack now benefits from changing nozzle sprites.

Why It's Good For The Game

The attack chain migration shall continue until morale improves.

Removes a respectable chunk of duplicated code.

The fine control of the new attack chain means you no longer bludgeon people when you are trying to extinguish them, hooray!

Backpack nozzle icon buff is good.

Testing

Put a fire extinguisher on Ian, they were able to fill it as normal.

Equipped regular and mini extinguishers. Spray function worked as expected. Did not attack unless nozzle was put away.

Equipped backpack firefighter tank. Cycled through all modes and tested them. Retracted nozzle. Worked as expected.

Equipped modsuit nozzle, repeated above. Retracted nozzle. Worked as expected.
