Rebased, and re-did the Box HoP shutters and blast doors and flash.
Created by: Jeroen52
Always got annoyed by greytides breaking down the HoP windows. I mean I can deal with them hacking the HoP's door but if they just go and be assholes and break windows while in the line.
This map change should deter them from being cunts, and also provides a bit more safety for the HoP.
Closes #12646 (closed).
Re-did this, because #12699 got merged while I was busy rebasing and re-doing this.
- rscadd: Added shutters and a flasher to Boxstation's HoP line.
