o Fixing core-library resolution for expression: ${plugin.artifacts} and ${plugin.artifactMap} (latter is keyed by g:a)
o Modified maven-core-it-plugin to accept something like "-DartifactToFile=org.apache.maven:maven-artifact"...it'll lookup that artifact in ${plugin.artifactMap}, and touch a file that's a mutation of the abs. path for that artifact.
o Added pomArtifact to ResolutionGroup, since the MavenMetadataSource ALWAYS creates a new Artifact for a pom...this allows us to retrieve the resolved Artifact for that pom.
