Handling name differences

[boldtrn]

As reported in #24, we should try to return the same name for every geocoder.

How do we handle the different name entry? E.g. we could parse "restaurant":"Sushi Oji" and use this as name but we would overwrite the full display name: "Sushi Oji, Prinzregentenstraße 122, 81677 München, Deutschland" and potentially break existing apps... hmmh

Using different geocoders will give you different quality but the fields should be the same information. So if it is a POI the name field should contain just its name not the full address and if it is a street, then it could just contain the street name etc. having a field all_name or display_name with all information could be a nice addition though, which we would need for photon too then.
