More Sculpture fixes and tweaks

- SCP can no longer be put into lockers. I had to modify the locker file
since all unlockerable objects already use that method
- He'll now take a LITTLE time to break down windows, which gives some
time for the target to wake up
- Can now open all doors naturally
- Sight was fixed, should now be perfect

Some things can still be fixed, notably you can still just get a
braindead to look at SCP to shut him down, but at least you can't
cremate SCP or weld him into a locker anymore
If I'm reading this correctly, if(G) doesn't do anything.
