change random event antag spawns to be based on dead players instead of dead antags

[babayetu83]

Now that I think of it...
This will start this mentality.

"I didn't roll antag, I'll die so I can respawn as antag"

Insted of respawning as a crewmate that "might" be a late join antag or sleeper agent or blob/flock mind.

it's pretty easy for admins to recognize those patterns of behaviors and confront people about that which as i understand is how they're so quick to catch ban evaders
