Cleanup E-EJB3 package/code/logging

This is E-EJB3 RC9. The following issues are not minor, they would make me feel uneasy if I was a user:

1. The bundled embedded-jboss-beans.xml uses xmlns="urn:jboss:bean-deployer" and everybody gets a nice WARN on startup that xmlns="urn:jboss:bean-deployer:2.0" should be used. Change that in the distributed configuration file.

2. [java] 13:40:10,676 WARN Ejb3Configuration:104 - Persistence provider caller does not implements the EJB3 spec correctly. PersistenceUnitInfo.getNewTempClassLoader() is null. It's OK to warn users that something is not right, but if something is not right in our distribution there should be a note in the README or something that tells me as a user that this is OK for the moment. Like a link to a JIRA issue.

3. [java] 13:44:59,381 WARN JBossTimerServiceFactory:112 - TIMER SERVICE IS NOT INSTALLED – Uh, yes, because I don't want it. Find a way for users to disable this warning. I don't see any way to disable the timer service in embedded-jboss-beans.xml and I don't want the .rar and .jar in my libs.

4. In RC9 there is code that prints debugging stuff on STDOUT:

[java] lookup
[java] UserTransaction: org.jboss.ejb3.embedded.UserTransactionImpl
[java] MessageHandlerBean: org.jnp.interfaces.NamingContext

This is triggered by EJB3StandaloneBootstrap.scanClasspath("helloworld-ejb3/build"), please remove from code...
