Particle attractors are visualized similarly to particle emitters,
except that they are shown as blue instead of yellow when parent system
is active.

Particle emitters are now visualized in 3D edit view either by
a small sphere for point emitters or by a proper model for
model based emitters. The visualization model is rendered
transparent. The visualization models can be displayed either
always or only when the parent particle system is active
in editor.
Trail emitters are not visualized, as any visualization would
be misleading, since these emitters follow generated particles.
