A simple mod that causes the player to only pick up part of an ammo pickup when they can't carry it all.
Limitations:
- Regrettably, I can't alter the pickup message on an item, so I cannot change the item's pickup message to reflect the fact that its amount has changed.
- Some ammo pickups don't work and I don't know why. (So far, I've identified the small ammo pickups from IronBound as one of the problematic ones.)
