names of squares

[emiltin]

the squares are important for navigation, and should be labelled.examples:

Rådhuspladsen: http://a.tiles.mapbox.com/v3/stamen.cphbikes.html#18.00/55.67609/12.56892

nytorv and gammeltorv: http://a.tiles.mapbox.com/v3/stamen.cphbikes.html#18.00/55.67800/12.57290

Added this to labels.mss to make them appear at z15:

#area-labels,
{
  [zoom>=15]
  {
    text-name: '[name]';
    text-face-name: 'Arial Regular';
    text-size: 12;
    text-halo-radius: 2;
    text-wrap-width: 32;
  }
}
