Account for multiple project dependency configurations and ideaExtraTestConfigurations

[orrsella]

If a project has multiple configurations used in dependsOn (for e.g: .dependsOn(testkit % "test,it")), they are currently converted to DependencyProject(testkit,CompileScope).

I would like to add the ability to account for multiple configurations (test,it) and also take into consideration the new ideaExtraTestConfigurations setting, checking if the configuration is a test one, and adding the dependency accordingly.

I have a working example that does this. Would this be of interest? Should I submit a pull request for such a feature?
