 #2848 - Removing the UUID from AkkaException
Switching to ByteString in FSMDocSpec to get rid of warnings in pattern matching
Let the ActorSystem find its configuration outside of the bundle, in the OSGi etc directory, following this order:
    etc/bundle-BUNDLE_SYMBOLIC_NAME.conf
    etc/bundle-BUNDLE_ID.conf
    etc/akka.conf
    akka-actor classpath config (using the original  OsgiActorSystemFactory.actorSystemConfig method.)

Configurations fallback from the most to the less specific one.

For the moment, as I haven't found test on ActorSystem Configuration in OSGi, I did not add test for this feature.
    	modified:   akka-osgi/src/main/scala/akka/osgi/OsgiActorSystemFactory.scala
Concerning akka in osgi:
ActorRefProvider contains in akka-cluster or akka-remote bundle are not found by the akka-actor bundle, thus exposing those if required
half-done PoC of typed channels
add selfChannel and createChildren
clean it up a little

- remove Parent trait and use ChannelList to describe the parent
- remove ugly hack and switch to erasure-based dispatch to the channels
- add parentChannel
- make ChannelRef a value class
