[Tilesathome] ROMA problems with relations

The main API will give you all relations that contain something that is 
in (or intersects) your bounding box.

It will not return the other members of these relations.

In that way it differs from the handling of ways, where nodes outside 
your bounding box *will* be returned if referenced by a way that is 
inside or intersects your box.

Not also that this is different from the relation/xxx/full API query, 
where you *will* get all objects referenced by the relation, plus one 
level of indirection for ways (i.e. you will also get nodes referenced 
by ways referenced by your relation).
