Magistrate and Psych Office shutter fixes

1) Remove the magistrate's office door shutters (http://nanotrasen.se/phpBB3/viewtopic.php?f=12&t=2695).
2) Fix the psych's office window shutters (http://nanotrasen.se/phpBB3/viewtopic.php?f=13&t=2732).

Two door changes:
1) Replace the magistrate/internal affair office glass airlock with internal airlock due to the privacy shutter being removed.
2) Replace the psych office glass medbay airlock with regular medbay airlock due to the privacy shutters serving no purpose when you can see through the doors diagonally.

Just a side note: I haven't committed to GitHub before, hence me accidentally removing and re-adding the back-up file (twice even). Shouldn't cause any issues, but let me know if it does.
