title: There are no housenumbers om OSM map
body: <p>I successfully installed tile server based on the instruction given in the switch2osm.org/serving-tiles/manually-building-a-tile-server-14-04/. So I have well-working web-server + tile-server. But there are no housenumbers on map. I add my next code in my imposm-mapping.py</p>
  
  <pre><code>buildings = Polygons (
      name = 'buildings',
      fields = (
          ('area', PseudoArea()),
          ('addr:housenumber', String()),
      ),
      mapping = {
          'building': (
              '__any__',
          ),
          'railway': (
              'station',
          )
          'aeroway': (
              'terminal',
          ),
      }
  )
  </code></pre>
  
  <p>In my labels.mss I have:</p>
  
  <pre><code>#housenumber [zoom&gt;=17]{
      ::label {
      text-name: '[addr:housenumber]';
      text-face-name:@sans;
      text-size: 9;
      text-placement: interior;
      text-min-dostance: 1;
      text-wrap-width: 0;
      text-fill: #444;
      }
  }
  </code></pre>
  
  <p>In default.style I have <code>node,way addr:housenumber text linear</code>.
  I saw question <a href="https://stackoverflow.com/questions/20685006/map-wont-show-building-numbers-tilemill-osm/20688689#20688689">Map won&#39;t show building numbers (tileMill + OSM)</a>. But I don't understand this tips.</p>
