[2.0.5.2508] Bug : Projectile changes flags upon being shot

[Spottswoode]

I'm not entirely sure this is a bug, but while attempting to create combining to projectiles I happen to notice that when the projectiles collided only one died and the other phased through actors and exploding on the wall.

---

I have fixed the code to detonate two DoomImpBalls when they collide into each other but firing into it still causes it to pass through actors.

I'm pretty sure that projectiles just plain don't have custom death states, however, that would not explain why they fly through actors. I also note that projectiles were not intended to do this, so I reiterate I'm not entirely sure if this is a bug or not.

Works fine with r3692.

[XutaWoo]

Don't projectiles not care about damage types? I thought that when a projectile hit another, they just blew up.

[Graf Zahl]

The damaging code doesn't care if the actor being hit is a projectile.
