Antag Dirty Bombs & Bodyhorror Parasites (#16317)

* dirty bombs & bodyhorror

* clean up + extra flavour

CE_ANTIEMETIC taken into account in the delayed_vomit() proc. doesn't need to subtract from CE_EMETIC anymore.

* desc. fix, TC tweak, syringe gun kit

* dirty bomb tweaks

radiation remains for as long as advertised (~8mins in an open space)
it also actually leaves behind the green goo now.
