Branch 2 3: RESTEASY-802

Added arquillian tests RESTEASY-802-AS71 and RESTEASY-802-AS72 to test GetRestful against old and new versions of AS 7.  RESTEASY-802-AS72 uses a homemade version of AS 7.2.0.Final, available from the JBoss nexus repository, and is currently commented out in the arquillian module list until an official version is available.
