(svn r18515) -Change: make it visible when you're to pass the next signal on danger and possible to cancel it

-Fix [FS#2891]: when you pass a signal at danger, in a PBS controlled area, don't try to do the 'safe' thing and stop, but continue going; the user wanted the train to pass the signal at danger so (s)he has to suffer the consequences. Ofcourse one can always stop the train manually.
