Subject: (svn r1525) -Codechange: rewrote the _order_array, now it can be made
 dynamic. -Codechange: renamed all 'schedule' stuff to 'order(list)'
 -Codechange: moved all order-stuff to order_cmd.c / order.h -Codechange:
 vehicles that share orders are now linked to eachother   with
 next_shared/prev_shared in Vehicle

  Developers: please use AssignOrder to assign data to an order. If not,
   you _WILL_ make the save-routine to assert!
