Title: Override default 404 route.

If ```Controller``` has it's own ```action_404()``` and method that doesn't exists inside controller will be called ```Controller->action_404()``` method will be executed instead default ```_404_``` route.
I don't know Fuel very well so no idea if that's the best way of doing that.
