Add grade 1 tracks to paved (#1485)

Browse Source 
This PR sets `surface=paved` for `highway=track` + `tracktype=grade1` if no other value of `surface` is set.  Roads tagged in this way are [generally paved](https://wiki.openstreetmap.org/wiki/Key:tracktype) and therefore encoding them as a paved road is appropriate.
