Mode 1710 - Connectors should be able to propagate changes in external systems via events 

Sorry about reopening but the first pull request was not rebased correctly:

Hola ModeShapers, 

https://issues.jboss.org/browse/MODE-1710 "Connectors should be able to propagate changes in external systems via events"
In Fedora4 this functionality is required in order to have projected nodes emit events, since we want an automatic queued copy mechanism for nodes which are atm projections but should utlimately reside inside modeshape.

Please contact us if you have any questions regarding this pull request.

Regards,
