detect emergency=permissive as bogus

[mkoniecz]

​http://wiki.openstreetmap.org/wiki/Key:access#Values

"permissive Open to general traffic until such time as the owner revokes the permission which they are legally allowed to do at any time in the future." (in this)

​http://wiki.openstreetmap.org/wiki/Key:access#Land-based_transportation

"emergency=* (category: emergency motor vehicles; e.g., ambulance, fire truck, police car)"

I am not aware about any country where owner may revoke access to emergency vehicles, most likely emergency=permissive makes no sense everywhere and probably it should be replaced by emergency=yes in most situations.
