(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
