O3 statue trigger

[ja2-derek]

Not sure if this should be classified as a bug or what.

In the code, the O3 statue trigger must be done in Room 4. In NightOps O3 map, room 4 is the northeast room in the central main building, so the trigger must be done there and it is quite far away from the statues.

The statues are no longer in a room in NightOps unlike vanilla, so there might not be an easy workaround. We may just add this somewhere in the README.
