better and more consistent action object naming

action queues now always contain the word "queue" after the action name
"action resumed" message now also specifies module type

which makes troubleshooting a bit easier. Note that we cannot output all
the config details (like destination etc) as this would require much more
elaborate code changes, which we at least do not like to do in the
stable version.
bugfix: "action xxx suspended" did report incorrect error code
