Adding SkullTag's runes: Questions!

[yum13241]

How I'd implement it:

1. Change Weapon.SisterWeapon to accept a numerical value. 0, 1, 2 and nothing all mean PowerWeaponLevel2 for backwards compat, and 3 would be PowerWeaponLevel3, which would be the Spread rune. The Weapon.SisterWeapon value would need to be the same obviously.

I'll file this off as 'DIY'.

Some weapons mods (like mine) already use PowerWeaponLevel2 for other things, I use it for an akimbo weapon. So unless ZScript can add new powerups, this is impossible to DIY while still having my guns akimbo for instance.
