Warning if using route=foot

[wernerschka]

What steps will reproduce the problem?

1. search for a relation: type=route; route=foot
2. change/add a tag and try to upload the changed route
3. JOSM creates a warning: "relation type unknown" (in German: "Relationstyp unbekannt")

What is the expected result?

Regarding to ​http://wiki.openstreetmap.org/wiki/Hiking#Tagging_walking_and_hiking_Route_Networks
route=foot is at least not depreciated and sometimes used for "easy, short" hiking routes (Walking). So as these type as an alternative to route=hiking long is not depreciated, JOSM should not create a warning.

What happens instead?

Please provide any additional information below. Attach a screenshot if possible.
