Place: include relations for related entities

[gythaogg]

Usecase:
Place A "contains" Place B (Place B "is located within" Place A)

1. Place A "is the place of composition of" Work1
2. Place B "is the place of activity of" Person1

In Place A's detail page, it should also be possible to see the second relationship above (which is between Place B and Person1) as Place B is located within Place A

This should work in case there is a Place C "is located within" Place B as well .. as all places located within B are also located within A.
