[Tagging] roundtrip

>From what I gathered during this discussion, roundtrip is mostly understood
and used wrongly by mappers.

It's also not something about the route, but rather about a passenger who
buys a ticket to come back the same way the same day/weekend and paying the
return fare on the same ticket (aller/retour - heen- en terug).

So I went and downloaded all objects tagged with roundtrip. The one I
changed needed major clean up in its members anyway.

So how do we get from a meaningless tag (roundtrip) to something that
actually has meaning for itineraries?

I think that on the one hand we need a tag to describe what the user can
expect (get back to approximate initial position) and on the other hand it
would be nice (for validation purposes) to know if the ways in the relation
are supposed to form a closed loop.

hence:
circular_route=yes
closed_loop=no

for that particular bus route.
