DEATH BUZZER

I'm categorizing this as a bug fix, though really it's more of a methodology fix.

In default Ace, you can cast revival abilities on living characters and non-revival abilities on dead characters -- the ability will just fizzle or bounce to another character. For me, that's fine mid-turn, but during actual ability selection I didn't want people to be able to whiff like that.

This is extremely simple. I haven't stress tested it too much yet, but it seems to work just fine so far. It should work with pretty much any other script.
