DBus runner servicename wildcard support

Summary:
A requested feature was to allow a runner to query N services for
results. i.e search through of all any konsole sessions.

Users can now set in the desktop file service=org.whatever.* and all
running services that match that name are queried for actions and
matching results. Only the service that provided the match will have
relevant "Run" method invoked.
