naturalearth admin countries zipfile contains a .txt file - millstone assumes wrongly it is a csv format

[kapouer]

Using this :

{
  "Datasource": {
    "file": "../shapefiles/ne_10m_admin_0_countries.zip"
  },
  "geometry": "linestring",
  "id": "countries",
  "name": "countries",
  "srs-name": "WGS84",
  "srs": "+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs"
}

Leads to :

<Datasource>
  <Parameter name="file"><![CDATA[/home/eda/cartographie/osmbright/shapefiles/ne_10m_admin_0_countries.txt]]></Parameter>
  <Parameter name="type"><![CDATA[csv]]></Parameter>
</Datasource>

There is indeed such a txt file but it contains only the version of the data.
Setting "type": "shape" in Datasource is a workaround.
