Bug: AuditManagerImpl does not update properties when updated from REST plugin

When updating some properties via the REST api, I noticed that some properties are not updated. After reading the code, I can see that the AuditManagerImpl classe does not implement the PropertyEventListener interface. I have modified, built and tested (mostly) code for making this change. Please assist me in helping get this issue resolved (aka, let me know if I need to do anything else).
