CRM-15066 fix - Choose to cancel one recurring contribution plan, but Civi cancels the other



https://issues.civicrm.org/jira/browse/CRM-15066
I like the idea of adding data-entity-action, but I don't like the idea of munging it in with the field id. I think supporting id-based properties is legacy and should be deprecated anyway. Can we just keep it simple and only support data-entity-action.
