12% chance of a ouija board spawning in the chaplain office. (#84615)

## About The Pull Request
The ouija board is quite fun, but it's found nowhere, with the exception
of Wawastation and the tranquility shuttle (by the time you get there
the round's already about to end), so I may as well make it possible for
other stations to have it sometimes.

## Why It's Good For The Game
The ouija board is fun, and ghosts are mischievous and misleading,
uncoordinated creatures most of the times.

## Changelog
