[Tagging] bus route with reversing

When I add a way/node which has already been added in a relation JOSM 
warn me and ask me to confirm or to cancel. So there is no issue with 
JOSM, or at least with the actual revision, to add more than once a 
way/node in a relation.

AFAIK order of members of type "way" in a relation of type route doesn't 
matter. The wiki states only that the stops should be ordered (a 
'should', not a 'shall'). But I think that to order the ways is a good 
practice and should be recommended also. Moreover nothing is stating 
that stops should be gathered in the relation or placed between the two 
ways it is linked to.

Finally, you can put "forward" and "backward" as roles of the ways to 
specify which way the route is taking. This is even more usefull when a 
way is added twice because the bus has to reverse. Please note that 
there is also forward:stop and backward:stop
