[QoL] Rescuing colonists should be prioritized above eating, resting, etc.

[psionicmushroom]

It seems like after events which leave colonists downed, their fellows will often prioritize their own less urgent needs over rescuing their downed allies. While this can be easily solved in-game with a little micromanagement, it seems a little unnecessary to have immediate colonist rescue be an opt in thing rather than the default.
