add "route" role (to presets?)

[mkoniecz]

According to ​http://wiki.openstreetmap.org/wiki/Relation:route#Members empty or "route" role should be used for ways making up the route.

Currently using empty results in "Empty role found" ( ​https://www.openstreetmap.org/relation/3717208 ) and "route" in "Role route unknown" ( ​https://www.openstreetmap.org/relation/3717144 ).

Probably the second version should be encouraged and should not result "Role verification problem" warning from validator.

There are a lot route relations with ways which have empty roles. In my opinion JOSM should not warn about this. Also the role "route" was not used from the beginning.
