Decentralisation of OccupyWeaponRange

[Nighthawk]

OccupyWeaponRange controls the range of all weapons when inside a garrisonned structure. Basically, no matter what the range is on the weapon, it will only ever follow this tag's value. I have two possible solutions.

1. Have a tag like:
Weapon.IgnoresOccupyRange= - this would make the game ignore OccupyWeaponRange for this weapon, and instead make it use the weapon's own range.

2. A different tag:
Weapon.OccupyRange= - A separate range tag used for when this weapon is firing from within a garrisoned structure.

The code related to occupiers firing out is really ugly, and a lot of it is tied to the first occupier. Can't really decouple it all without headaches. Additionally, there'd be a need to change the firing loop when not all occupiers can fire at a target, and that's no fun either.
