TODO removal Vol 2.
Travis CI support for Scala 2.11
Removed activator template version from build.properties
Json test fixed
Orchestrator test launching the whole app added

Manually launching "sbt run -c ... -o ..." is no longer necessary. The
functionality is now contained in the OrchestratorTest". Therefore, H2
is now just a test dependency, not runtime one.
