Makes the singularity engine actually work stably. (#4068)

* Add GNU Octave script for tuning singularity engine. startsingularityengine is now properly tuned & sets up radiation collectors. FTLize RadiationCollectorComponent.

* Fix bugs with radiation collectors producing infinite power.

* Ensure singularities don't instantly annihilate other singularities (causing new singularities to instantly dissolve)

Technically found by a "bug" where a singularity generator would make multiple singularities, but this renders that bug harmless.

* Tune singularity shield emitters to hopefully randomly fail less, and add an Octave script for looking into that

* Fix singularity shader

* Map in an unfinished PA into Saltern

* Correct PA particles being counted twice by singularity calculations, add singulo food component

* Hopefully stop "level 1 singulo stuck in a corner" issues by freezing it when it goes to level 1 from any other level

* Apply suggestions on 'jazz' PR
