CheckReplacement Doesn't Honor A_BossDeath

Using the new CheckReplacement feature can break any map that relies on A_BossDeath, such as Doom II MAP07.

Running the example Marisa posted, killing Archviles in MAP07 will not activate any of the doors/platforms that killing Mancubi and Arachnotrons should.

This isn't actually something new. It happens even if you do replacement by using the "replaces" keyword in DECORATE and ZScript. The Archvile directly replaces both of those monsters, yet doesn't call A_BossDeath on death, so there is no way for it to trigger those specials.

The new replacement system cannot honor A_BossDeath, it's a technical impossibility. If you need handling for that the RandomSpawner is the only option.

I forgot about that. Good catch, thank you.

I'll work around it, then. Thanks again.
