Recreation Work Type

Adds recreation as a work type. No more idle pawns!
Details
This is a completely new work type and doesn’t change how vanilla recreation behaviour works.
If a pawn is prioritized for this work type, they do recreation just like they do in vanilla. The difference is that they won’t stop even when their recreation need reaches 100%.
Pawns will avoid ingesting recreation-giving consumables (such as chocolate, insect jelly, beer, or ambrosia) if doing so would raise their recreation need above 100%. This applies only to this work type.
It may improve performance if your colony has many idle pawns.
