o Adding ${plugin.*} expression support for mojos. Specifically, added support for ${plugin.artifacts} to retrieve the plugin's classpath artifacts. NOTE: There may be artifacts which are FILTERED by the resolution process, since they are provided in the maven distro. NOT SURE HOW BEST TO RESOLVE THAT...but it'll cause problems with people forking certain mojos, undoubtedly. 

May resolve: MNG-455
