* Remove references to old singularity machines (#53509)
Removes the singularity generator and the particle accelerator. The former had no sprite, and the latter only existed because of a leftover type path. This does not affect gameplay at all.
Removes the "Start Singularity" verb that was only intended for debug use.
Fixes#53508.
