Allow Firemen to wear clothing.

[Alfred]

Why: 
- Paramedics can wear clothing, so why should Firemen be restricted.
- The Fireman model is old and out of date, if we cannot find a newer one we should at least allow players to wear custom clothing.
- Some suits (such as the gas mask), would be perfect for Fireman RP. E.g. Entering burning buildings or areas would require a gas mask in real life.

They should make some special clothing just for Fireman, such as as gas mask you can equip when entering a burning building but it be different to the current one, something only for Fireman and more realistic.
