integTest and IntelliJ Idea output dir

[remy-tiitre]

Right now if you have unit tests and integration tests (integTest facet applied) and you are using IntelliJ then they both output their classes to out/test/main folder. Which is not good, as they could have name collisions. I think that every facet should actually write its stuff to a different output folder. Its not a problem when you delegate all the builds to gralde in IntelliJ, but for performance reasons not everyone is doing that and some rely on IntelliJ build functionality.

In addition, Gradle outputs to the build directoy by default, why not use that?
