(svn r10298) -Fix [FS#903]: show the subdirectory below the default data directory in this filename in the newgrf list. The directory was removed in r9560 because then it used to full path instead of the path relative to the data directory, but since the inclusion of "search paths" that is not necessary anymore.

<span style="font-weight: bold;"></span>Six attributes hold the information about a tile.
This can be seen in the <a href="landscape.html">Landscape</a> document. This page tries to give an overview of used and free bits of
the array so you can quickly see what is used and what is not.
<ul>
<li><span style="font-weight: bold;"><span class="free">O</span></span> - bit is free</li>
<li><span style="font-weight: bold;"><span class="used">X</span></span> - bit is used</li>
<li><span style="font-weight: bold;"><span class="abuse"> </span></span> - bit of attribute is abused for different purposes</li>
</ul>
<p>
<ul>
<li><span style="font-weight: bold;">type_height</span> - 8 bits in size, stores tile height (lower 4 bits) and tile class (upper 4 bits)</li>
<li><span style="font-weight: bold;">m1</span> - 8 bits in size, used to identify the owner of that tile (eg piece of rail, bridge, etc.)</li>
<li><span style="font-weight: bold;">m2</span> - 16 bits in size, used to identify the index of the given tile (object) in the (object-)array</li>
<li><span style="font-weight: bold;">m3</span> - 8 bits in size, is used for general storage</li>
<li><span style="font-weight: bold;">m4</span> - 8 bits in size, is used for general storage</li>
<li><span style="font-weight: bold;">m5</span> - 8 bits in size, is used for general storage</li>
<li><span style="font-weight: bold;">m6</span> - 8 bits in size, special meaning : lower 2 bits only valid in tropic climate, upper 2 bits for bridges</li>
<li><span style="font-weight: bold;">m7</span> - 8 bits in size, is used for general storage</li>
