Initial stab at running integration tests against JBoss EAP

For now you need to download jboss-eap-6.1.0.Alpha.zip and place it in
the integration-tests/ folder. To run the integration tests against EAP,

cd integration-tests
mvn test -Dtorquebox.slim=false

The version of EAP tests are run against can be changed by setting the
version.eap system property:

mvn test -Dtorquebox.slim=false -Dversion.eap=6.1.0.Beta

There are still several integration test failures, mainly around the
torquebox-cdi module.
