Hi all,

attached patch implements the new internal tag
mkgmap:add-to-NOD=false
to handle the issue discussed here:
http://gis.19327.n5.nabble.com/don-t-route-through-highway-construction-tt5856734.html

It shows how to use it in the default style.
I've also added a rule to ignore highway=planned like highway=proposed

If you don't like the rather technical name mkgmap:add-to-NOD, please let me know it,
here are my ideas for alternatives:
mkgmap:ignore-for-routing=yes
mkgmap:routable=no
mkgmap:address-search-only=yes
