Wip/elucidator integration merge

To simplify things I have created this specific branch in which I have already merged with master. This is the equivalent of the integration between wip/elucidator-integration and master.

Highlights of PR:
* uses Echo instead of Atmos
* applies "echo:run" on every program that is run in Activator
* implements a clear cache functionality for removing data from Elucidator (the in-memory stats)
* massive refactoring of Play side for Console 

Still some things that need to be polished a little (see Trello cards). I'd rather get this into master now than wait for everything to work 100 percent. This way the whole team can test things out and suggest improvements/changes before we ship the 1.1.0.

Please note that this PR uses sbt-remote-control from the 1.1.x series. So merging it into master basically means that we up that version. Should be okay, right?
