RTGOV-161: simply db configuration
           using @PersistenceContext to inject the EntityManager.
Added transactional interceptor to test managing txn scope around activity server impl methods
Merge branch 'rtgov-161' of git://github.com/jeffyu/rtgov into RTGOV-175
RTGOV-175 Apply CDI transactional interceptor on top of RTGOV-161 db simplification work - currently transactional annotation and interceptor defined with activity server impl, but needs to be moved to common module (RTGOV-176)
RTGOV-25 Update to includea 'process variable set' activity in the model
RTGOV-25 Interim commit pending outcome of SWITCHYARD-1393/1400
Phase one of upgrade to jbossas7.2/eap6.1 - core modules now compile, still need to test against server with arquillian
RTGOV-177 Update to baseline on EAP 6.1 and latest switchyard 1.0 snapshot. Currently issue running arquillian tests under release/jbossas/tests, due to bug in (or incompatible versions of) shrinkwrap and/or sonatype aether, not allowing maven dependencies to be resolved from local repo. Also seems to be a problem with swyd when sending a request for an unknown item - needs further investigation
Remove default infinispan config, as seems to be sensitive to schema version, which has changed between as7.1.1 and as7.2 - so better not to include
Used Resource injection in some places to help with managing runtime dependencies. Added support for capturing exchange based activity events via the event listener mechanism
Fixed arquillian test issue, due to shrinkwrap/aether incompatibility, so now tests run again against AS7.2
Update arquillian tests to run against EAP 6.1
RTGOV-186 - Move the call trace processor into a CDI service, and provide a transactional interceptor to manage a transaction scope that also encompasses the activity server impl
Fix exceptions logged when running the custom events arquillian tests

Some checkstyle fixes
Fix remaining checkstyle issues
Update readme to indicate rtgov now requires swyd 1.0
RTGOV-180 Make the ordering of service nodes and operation nodes consistent across refreshes. Also just display local name when fully qualified java interface name
RTGOV-182 Refactor activity interceptor to be an explicitly invoked activity validator mechanism
RTGOV-182 Update policy sync example to use new validator mechanism
GS-41: move the rtgov related gadgets in rtgov project.
