Publishing: Remove some operations from the Channel and ChannelType interface that really shouldn't be exposed. Also removed the PublishingQueue interface - the two operations it had are now on the PublishingService. WQS: Removed obsolete references to publishing channels. git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@30794 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
