- Updated web services, SDK and web client where appropraite - Patch added to migrate existing rules - Entire rule service can now be disabled programmatically - Rule service is now disabled during the patching process - StoreEnum and languageEnum types removed from web service interfaces - Multiple rule types now supported in the repo (but not in the UI) - Removed owning node ref from action and rule .. now calculated from methods on the rule service git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@3464 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
