Sense of Urgency

Adds a high-priority "Urgent" job category to make colonists prioritize urgent problems. No more colonists ignoring dead generators or going to bed while their colleagues are bleeding out on the floor.

Urgent jobs include:
- Refueling empty generators
- Rescuing colonists who are bleeding out
- Refueling expired camp fires and passive coolers
- Rearming empty turrets
- Feeding starving patients and prisoners
- Charging flat mechs
- Cutting blighted plants

Also adds the following optional behaviour (enable/disable in mod settings):
- Doctors prioritize tending patients by need
- Hunters prioritize target animals - strong hunters prioritize dangerous game and vice-versa

Compatible with Complex Jobs and Common Sense.
