title: Slick2d's TiledMap.getTileProperty's String "def" field
body: <p>I am trying to use Slick2d to write a basic game am using the Tiled tilemap editor to make the game terrain.  Each type of tile in the map has a property known as "id" with a known string as a value.</p>
  
  <p>I am using Slick2d's method:</p>
  
  <pre><code>TiledMap.getTileProperty(int tileID, java.lang.String propertyName, java.lang.String def)
  </code></pre>
  
  <p>to get the property of an individual tile.  I believe my implementation works, but does anyone know what the "def" field should be?  I think propertyName should be "id" and tileID being the getTileId method.</p>
  
  <p>Thanks a lot!</p>
