[REQUEST] Extend ItemType and WeaponType to be able to handle more than 32 entries

[Enduriel]

This will be painful to manage around backwards compatibility but is important since it has been hit in practice by legends team

Ideally I'd want WeaponType on weapons to be a weighted container to be able to specify what is the "main" type of a hybrid weapon e.g. whether it is mostly a spear with some sword characteristics (e.g. Swordstaff) or mostly a sword with some cleaver characteristics (e.g. Kriegsmesser). This can be helpful in modding when you want to do certain things based on the dominant weapon type of a hybrid weapon.
