(svn r1493) -Codechange: Removed redundancy in the order GUI. Currently we had most
of the code written 4 - 8 times in the code.
This currently causes the "non-stop" button to appear for all
vehicles, which is disabled all the time. Don't report this as a bug
please.
This is (hopefully) the first patch in a joint effort to simplify
the order system
