jboss-classpool.jar and jboss-classpool-scoped.jar should be copied to client dir and included in jbossall-client.jar's MANIFEST.MF Class-Path

We were getting the following exception when trying to connect from the RHQ Agent to AS M3 via JNP:

Note, the exception occurs on a the call to InitialContext.lookup(). We never saw this in AS 5.x. I was able to get past the exception by adding JBOSS_HOME/lib/jboss-classpool.jar and JBOSS_HOME/lib/jboss-classpool-scoped.jar to the RHQ Agent's classpath. 

So these two jars are now apparently required in the client classpath for the following basic JNP based lookup of the ProfileService to work:

        Properties env = new Properties();
        env.setProperty(Context.PROVIDER_URL, "jnp://127.0.0.1:1099/");
        // Always use the non-login context factory, since we'll use JAAS for authentication if a username/password was
        // provided.
        env.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");       
        InitialContext initialContext;
        try
            initialContext = new InitialContext(env);
        } catch (NamingException e) {
            throw new RuntimeException("Failed to create JNDI InitialContext.", e);
        }
        ProfileService profileService = (ProfileService)initialContext.lookup("ProfileService");
        

Since this is the case, I think these two jars should be copied to JBOSS_HOME/client/ and also included in JBOSS_HOME/client/jbossall-client.jar's MANIFEST.MF Class-Path, to emphasize that they are needed for client connections and so that existing client code that uses jbossall-client.jar will not have to be updated to also include these two jars.
