Allow us to apply red alert priority to incapacitated dupes

[Zarquan]

One of my dupes decided to wander in to a volcano.  This was very far out of the way and near the end of the main work shift, which is about when dupes started going to sleep.  This led to the dupe dying, even though there were dupes somewhat in the area because I couldn't get the dupes to prioritize saving that dupe over their own wellbeing.  Some of the dupes went over to save them, but ran out of breath on the way and turned around.  When I activated red alert, they did not go to save him because there were other high priority tasks in my base (because I happened to be leaking atmosphere at the time).

If I could have put the emergency priority on the dupe, then I could have saved him.

I think that they save incapacitated duplicants 24/7 as of a recent update.
