Workaround for Maven-2 compatibility.

* Use String parameters and Enum.valueOf methods because old versions of
  plexus-container-default used in Maven-2 do not include a EnumConverter.
* Add implementation hints in POMs because Maven-2 is unable to guess
  implementing classes correctly.
  See http://blog.sonatype.com/people/2011/03/configuring-plugin-goals-in-maven-3/#.UpkF45FIhsp)
* Use concrete type ArrayList instead of List in MergeMojo because Maven-2 is not
  able to deduce a corresponding class for an interface.
