IDEA 7x: add resources directories to classpath

Since Buildr 1.3, resources are no longer merged with classes into the target/classes directory.
They now have their own target dir: target/resources, target/test/resources.

However IDEA doe snot support multiple output directories, which means that only target/classes and target/test/classes are included in "Run/Test configurations".
Resources are ignored, and not added in the classpath. Thus Run/Tests fail.

The fix is to add target/resources, target/test/resources as module dependencies in the module definition file.
