Make Singulo Stable Again (#4521)

* Make Singulo Stable Again

* Prevents emitter beam effects from being pulled by singulo.  Now watch them hit the field gens.
* Prevent singulo from consuming the PA particle effects.  It already gets fed by impact, don't try to eat them.
* Improve the Setup Singularity debug verb to do more better setup (including PA)
* Fix the energy dissipation values so that singularity does not just keep on growing even when setup properly.

* Enhance singularity proc/eat()

* Use `var/simulated` as a more generic way to ignore lighting overlays etc
* Remove redundant code in the rest of the proc body.
* Slight optimization: avoiding typecheck in loop over return from orange()
