community\transport tag processing changed: 1) CommunityData and TransportTarget classes now take optional    tag and tagList initializers respectively 2) NotificationOriginator.cfgNtfOrg() method does not take tagList parameter    anymore but uses tag values carried by CommunityData and TransportTarget    instances 3) If no tag information is specified, use TransportTarget instance hash    as a tag which binds CommunityData instance with TransportTarget instance    (the above is needed for notification generation)
