QPID-2005: make the fanout exchange mbean return a single wildcard binding entry with all queues listed.

Modify the management console to auto-select the wildcard binding when the exchange is viewed. Also, suppress the warning on entering no binding key when creating a fanout exchange binding, but auto-fill the field with the wildcard for clarity.
