Setting up a Scala sbt multi-project with Cassandra connectivity and migrations

This is a from-the-trenches tutorial about some of the first things I have managed to understand about and build with Scala. My goal is to provide a detailed step-by-step tutorial which shows how to set up a new Scala project with two sub-modules (one being plain old Scala, one being based on Play2) using sbt. I’ll also describe how to enable both modules to speak with an Apache Cassandra database, and how to add automatically applied database migrations (in order to allow using the project in a Continuous Delivery setup like the one we use at Galeria Kaufhof).
