[fixed] Blood decals aren't affected by dynamic lights

[Nash]

In a totally dark room (0), the decal appears black, even though there's a dynamic light near-by.

EDIT: They appear totally black in Doom lighting mode. They look better in other lighting modes though (some red visible).

EDIT2: However, even in other lighting modes, blood decals appear totally black when the room lighting is 0, even with a bright white dynamic light illuminating the room.
