Tutorial: Rotating Brush Models for QuakeWorld

[r00k]

Just once, as you still need to offset the end for the hull, whether the bmodel has rotated or not.
Adding else after checking the entity, says not to update the trace.endpos by offset just because its turned.

There's an unconditional VectorAdd in baker's rotated trace though, hence why his version has the else, and yours should not.
