(svn r6161) -Feature: List of vehicles with the same shared orders
the list is available in the orders window and looks like the list buttons from the station windows (small vehicle)
The button is disabled if the vehicle do not have any shared orders or it got shared orders, but an empty order list
based on a patch by nycom, thought it ended up getting heavily modified
Thanks to TrueLight for proofreading and suggestions

<h3 style="font-weight: bold;">Landscape</h3>
<span style="font-weight: bold;"></span>Five 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">&nbsp;</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>
</ul>
