Title: Removes Exec['reload-nginx'], because Service['nginx'] can also do the thing.

I just think that it is more intuitive to write notify Service, than using an additionally defined Exec thingy. It is also on the road-map to really support Service with refresh option (http://projects.puppetlabs.com/issues/1014) right now, you can just set "restart => '/etc/init.d/nginx reload'" and it does what you expect.
