o Added maven-plugin-mapping project to handle repository metadata that contains prefix-to-artifactId mappings for groups of plugins
o Added builder classes for plugin mappings
o Modified maven-artifact and maven-artifact-manager to handle the concept of repository metadata in addition to artifact metadata.
o Added pluginGroups section to settings.xml, new code to merge these lists of plugin groups, and a unit test to ensure that this merge is taking place properly.
o Added maven-plugin-mapping to dependencies of maven-core, along with the list of builds to be performed by mboot.
