Change the AutoDeploymentService.updateExternal(String,boolean) to return an ArchiveEntry

The jboss-deployer in the ServiceMix Extensions repo at the Codehaus has a class named JBIService.uninstallArchive() that used to utilize the JBIContainer.removeArchive(String) method whose signature has been changed to JBIContainer.removeArchive(ArchiveEntry). Being that ArchiveEntry is a static internal class to AutoDeploymentService it would be easiest to keep it contained there. So the easiest solution for the jboss-deployer's JBIService.uninstallArchive() method is to change the return type of the AutoDeploymentService.updateExternalArchive(String,boolean) method from void to ArchiveEntry to faciiitate the JBIService.uninstallArchive() method.
