[mkgmap-dev] Building northeast map

Hi Gerd,

I found the first issue why so many cities were missing. It turns out in my area many boundaries contain 'place_name' instead of 'name'. Examples: http://overpass-turbo.eu/s/5HL

I realize I could add this tag to name-tag-list, but i think it would be better to have it searched as a last resort. Thus, I propose the following patch:

Index: src/uk/me/parabola/mkgmap/reader/osm/boundary/BoundaryLocationPreparer.java
===================================================================

+			log.warn("Boundry has controversial place_name:", place_name, tags, "http://wiki.openstreetmap.org/wiki/Proposed_features/drop_recommendation_for_place_name <http://wiki.openstreetmap.org/wiki/Proposed_features/drop_recommendation_for_place_name>");
+			return place_name;
+		}
 		
 		return null;
 	}

Secondly, while I don't have a complete admin_level2 in my boundary file, most city, county and state boundaries contain is_in tags. For example, Danbury (http://www.openstreetmap.org/way/33271879 <http://www.openstreetmap.org/way/33271879>), contains 
is_in:country <http://wiki.openstreetmap.org/wiki/Key:is%20in:country?uselang=en-US>	USA
is_in:state <http://wiki.openstreetmap.org/wiki/Key:is%20in:state?uselang=en-US>	Connecticut
With these tags, I should be able to set state and country information even if I don't have those boundaries explicitly loaded. I was thinking this extra information could be added to the BoundaryLocationInfo class, much like how the zip code is today. What do you think about that approach?
