Add Unique Caps

[LordPeter]

Implement unique caps for all the "hidden" spawns, e.g. hunting, fishing etc.

• implement caps
• actually include any meaningful interaction with them

[LordPeter]

Not sure what to do about "meaningful interaction"... atm I'm out of ideas and they are pretty barebone, just hidden. Overhunting etc seems not to have existed during the Middle Ages, so that idea is gone for good.
