Functionnality : Create short url from Facade

[Nuranto]

For the same use case as in #13

If you're OK with adding those functionnalities, tell me if you want me to work on it, or if you prefer do it by yourself :)

That could maybe be useful

Another small bug interesting thing : An helper function route_shorten that basically calls route helper, but returns the shorten url result.
