RFE: add 'Triage' as a medical equivalent of mass repair/mass salvage

[SuperStucco]

With large deployments of infantry, both player and in scenarios like Irregular Forces, there can be masses of casualties beyond the capabilities of the force or at least enough to make user management time consuming. It would be useful to have a medical equivalent of mass repair/mass salvage e.g. 'Triage', that automatically assigns patients to doctors based on injuries and doctor skill level.
