Adds more biohazard shutters to science because only having like 3 locations with them is totally useless, like really you can just walk around it

Created by: Jeroen52

I got annoyed at how the Biohazard Shutters in Science were inconsistent and easy to evade. What I did was redesign some places in Science to accomodate for the Biohazard Shutters. I think that it looks somewhat decent as some areas like Telesci and Mech Bay were challenging, criticism is welcome. Xenobio is blocked off from Science and the rest of the station when doing the lockdown, but there are no safe way for Science to cross into the Science hallway without coming in contact with a maintenance tunnel. And Xenobio is pretty much the only Biohazard in Science, I'm wondering why their entire distro isn't separated from the outside world.

Check the changelog for all changes in Science.

Here is a screenshot of the changes, you can see shutters all over Science, as the previous ones were pretty much useless.
