(svn r7559) -Fix (FS#456): clicking the 'Full Load' button when the 'current' order is selected in the Order GUI and one has instructed the train to go to the depot, via the button in the Train View GUI, changed the depot order by switching from 'service at depot' to 'stop at depot' and vice versa.
