Singularity Fixes, Part 3 (#4105)

* Hopefully make singularity shader warping resolution-invariant

This may or may not fix intensity issues

* Fix singularity 'zero velocity' check

It got stuck in a corner. Twice. I really thought I'd fixed that.

* Make it easier to move around various power stuff by shrinking their AABBs a little and making singulo generator a circle

* Changes to some machine prototypes to reduce duplication of collision changes (#1)

* Changes to some machine prototypes to reduce duplication of collision changes

* BaseMachine.BaseMachineUnpowered -> BaseMachine.BaseMachinePowered
