distance-based job control

[LCCX]

I'm not exactly sure how this would work, but I'd really like pawns to be "smarter" about efficiently completing as much planned work as possible. Having them cross the map to harvest 3-4 plants and then returning to eat a meal without even bringing the just-harvested materials back with them is just so sad. Maybe when manual priorities are set then distance-to-job could take precedence over the default activity ordering?
