Barrel explosion do not cause damage to player or monsters

[VortexAcherontic]

Summary

Whenever a barrel explodes it does not cause damage to players or monsters.

Possible symptoms

I suspect this is a similar issue as like with #15 (fixed in #23), as well as the TripBombs not inflicting damage (fixed in #23 ) and the marine in zbase1 not being killed by the gunner explosion (fixed in #23) by wrong usage of T_RadiusDamage.

Even tho I will probably looking into this myself I still open this issue to not forget about this :)

Same issue with player's grenades and rockets not causing damage to a player or nearby monsters. The damage to monsters is caused only if hit directly, so throwing grenades from around the corner makes no effect.
