added new feature for route management

in the route management tab under settings, you can now design a route.
the default route order for new stops will be zero. four buttons are
present: first, up, down, last. they will put a stop: as first on route,
up one position from current one, down one position from current one, at
end of route. also deprecated the default method as the current way of
handling what stop the load for otherclient is by finding the first
student stop and using that.
