Support the notion of shrinkwrap BundleArchive

Currently we create test bundles like this

final JavaArchive archive = ShrinkWrap.create("test.jar", JavaArchive.class);
archive.setManifest(new Asset()
{
public InputStream openStream()

{ OSGiManifestBuilder builder = OSGiManifestBuilder.newInstance(); builder.addBundleSymbolicName(archive.getName()); builder.addBundleManifestVersion(2); builder.addBundleActivator(SimpleActivator.class.getName()); // [TODO] generate a separate bundle the contains the test case builder.addExportPackages(OSGiEmbeddedFrameworkTestCase.class); builder.addImportPackages("org.jboss.arquillian.junit", "org.jboss.shrinkwrap.api", "org.jboss.shrinkwrap.api.spec"); builder.addImportPackages("javax.inject", "org.junit", "org.junit.runner"); return builder.openStream(); }

});
archive.addClasses(SimpleActivator.class, SimpleService.class);
archive.addClasses(OSGiEmbeddedFrameworkTestCase.class);

This should be done much easier via a BundleArchive
