P.S. After consulting with Friendly_Ghost / Casper, I'll put the GNIS 
feature ID on the relations / ways, because sometimes it's useful to 
check data from GNIS website. But yeah, if the import needs to be 
improved, or reverted because it doesn't meet the level of OSM, leave me 
a comment on the changeset, which i'll provide soon.
