Projectile hit efx surface differential

[Silverfang22]

Blaster, slugthrowers, projectiles in general should play different efx dependent on what surface they hit.

Flesh, shield, and droid hit efx for player and NPC characters are already present in the game files.

Certain surface parms in bsps should also play different efx, perhaps the simplest way to do this would be to play an additional efx for some surfaces, such as splintering wood.

Perhaps we could have the efx reference (code likely needed) whatever shader it hits as its texture to map to the particles so it matches any color wood you hit.
