Hotfix to recent organ changes

- Unfucked the Bioprinter a little. It can now be anchored and deanchored using a wrench, has luminosity, uses power, has density (who the fuck forgets this kind of shit) and now uses visible_message fully
- Added three spare adv. trauma kits to Surgery. This should last the round unless a lung-popping virus starts propagating
- Commented immulsion-ruining messages. Finish the code first, no need to tell players that an action is a WIP

I will keep to hotfixes. Many things could have been done, notably making the bioprinter constructible, but since this whole thing is a WIP port I'll stick to unfucking what I feel is urgent (okay, making the machine luminescent is not urgent, but at least it's done)
