Added m2e lifecycle mapping for the maven-antrun-plugin.  The test Tomcat containers should now be downloaded on incremental builds when working solely in Eclipse.  Initial testing has shown no build loops or performance issues, but if this proves to be a problem the execution can be changed to run on full builds only, or not at all.  Either way there should be no more build errors reported in Eclipse in lieu of undocumented workspace or settings.xml configuration.
