* Add test verifying mapError matching on parent class
* Add to Source, SubSource and SubFlow as well
Introduces a materializer started through an extension and then an implicit
conversion for Scala turning an implicitly available ActorSystem into a
materializer. The Java APIs has been ammended with run-methods accepting
an ActorSystem.

When a Success is received, call onCompleteThenStop instead of just
context.stop; that takes care of the completion logic instead of just
stopping the actor and leaving the stream going.
Add test to ensure the stream materializes on Source.actorRef receiving
Status.Success
Remove tests around stream completion behaviour in response to
PoisonPill - as well as these tests not correctly demonstrating that the
completion was passed on downstream, they describe behaviour which was
previously incidental and is no longer accurate.
Update the docs to reflect that PoisonPill should not be used on the
actor ref as this scenario will necessarily result in bad behaviour as
it will be unable to signal the completion downstream.
Make a few grammar fixes and remove some trailing space while updating the
docs.
