Ability to add event handlers via configuration.  Changed arguments of event handlers to req and res so events can be used to handle anything from notifications to audits.  Event handlers updated to get their configuration via an options parameter that is passed to constructor.  Add sample consoleAuditHandler.

Added httpAuditHandler that writes audits to a eCrud instance.
Added configurable option to limit the number of records returned by getCollection and getFiles.
