Hi all,

Today I finally tracked down and fixed an annoying navigational glitch where commuters sometimes remain stuck to a turnstile exit. This looks to be down to a problem with them recording if they had used the turnstile before. I've altered the way they choose to use turnstiles slightly so this should prevent that.

A few other things too:

-cannot place doors for rooms if the outside door cell is occupied by solid
-in windowed mode, windows remember position between saves/loads
-Commuters can use turnstiles more than once. Prevents nav bug where commuters sometimes got stuck on turnstile exits
-addressed possible issue with crash placing room door
