[UPDATE] Catharsi & Source Guardian

Updated the Catharsi and SourceGuardian as the detonator was using A_Die to call the explosion sound. This was causing (G)ZDoom to crash to desktop.

I found that the A_CustomMissile calls in the Spawn state of the guardian's detonator are kind of useless (this has nothing to do with your changes). The detonator in most cases explodes before reaching those calls, something to do with how Doom-style bouncing kills the projectile when it loses momentum, I think.

The Catharsi's detonator didn't cause any issues when testing it (the version currently on the repo), which to be expected, since A_Die will kill it, making it play its death sound, anyway.

Update: the change that was introduced to A_Die to handle killing projectiles* was reverted , and as a result, these monsters (the Source Guardian, at least) won't cause the engine to crash anymore.

And since the only change that was introduced here was to fix the crash issue, which is no longer a problem, I'm closing this.

I'll probably make a "maintenance" update for these two monster submissions later on.
