Improvement: Removing reviving from medics

[DviddLeff]

While I think reviving is a small problem, I certainly do not want to see it removed.

I fully support a system where head shots prevent revives, along with a coupe de grace style execution of fallen enemies so that once they go down, they stay down.

I'd also like to have the death camera follow the players view as they fall until they choose to revive or respawn.
