routing_demo : not up-to date with riot v2.3 beacuse of routing problem

[rvion]

according to here: http://riotjs.com/api/route/#riot-route-start

Riot doesn’t start its router automatically. DON’T FORGET TO START IT BY YOURSELF. This also means that you can choose your favorite router. (Note: before v2.3 Riot started the router automatically. The behavior was changed)

riot.route.start(true)
