Typed only on Scala 2.12

* Typed modules not compiled on 2.11
* Dependent modules also not on 2.11:
  * docs
  * akka-bench-jmh split into a separate one for typed

Still doesn't work because something with sbt

+This subproject contains some microbenchmarks excercising key parts of Akka Typed.

+You can run them like:
+
+   project akka-bench-jmh-typed
+   jmh:run -i 3 -wi 3 -f 1 .*ActorCreationBenchmark
+
+Use 'jmh:run -h' to get an overview of the available options.
