Added parameter validation to RootActorPath
===========================================
Previously ``akka.actor.RootActorPath`` allowed passing in arbitrary strings into its name parameter,
which is meant to be the *name* of the root Actor. Subsequently, if constructed with an invalid name
such as a full path for example (``/user/Full/Path``) some features using this path may transparently fail -
such as using ``actorSelection`` on such invalid path.
In Akka 2.4.x the ``RootActorPath`` validates the input and may throw an ``IllegalArgumentException`` if
the passed in name string is illegal (contains ``/`` elsewhere than in the begining of the string or contains ``#``).
Advanced Notice: TypedActors will go away
