Bug fixes

Adding DependencyStack tracking for dependencies which need additional processing. The DependencyStack will no longer return "TRUE" for hasDependencies() method calls if any of the passed dependencies require additional processing.

Most stable version. Includes work from #3038533: Make layout configuration available.
