Radiation fixes to Singularity and ling QOL changes

Created by: mtpowell

Singularity was applying direct toxin damage in addition to radiation damage, essentially doubling the damage. I removed the toxin portion and applied a check against the users suit radiation resistance for the radiation damage.

Supermatter wasn't taking into account the users suit radiation resistance, so I applied the same check here.

The Supermatter is relatively the same, the Singularity will apply the correct amount of radiation without knocking you unconscious in one tic.
