Fixes issues #1309 and #1339
Changed the name of the config section to AuditConfig, added a powershell
commandlet to add this config section quickly and added extra warnings when values are specified in the UnicastBusConfig
Modified the acceptance tests such that only the audit specific ones will
trigger message auditing. Also made the tests generic for all transports.
Making sure that the audit queue will be created when the installers are
invoked.
