prevent dwarves from cooking tallow or alcohol. automatically cook lavish meals based on all ingredients, not just plant growths.
refactor labor management code. prevent error message about lost tools. unassign labors from busy dwarves only if there is a sizeable workforce.
spread out gather area creation over time to prevent a long delay at startup. fix some cases of the wrong tile being returned by surface_tile_at.
reduce the number of detail/herbalism jobs. allow all dwarves to be haulers simultaneously.
