Introduced module configurtion for end-users.

Using a basic "Sign-up Configuration" as it emerged from
the Wikidata Topicmaps UI use-case.

New concept:
Configuration topics get directly associated to the modules "Plugin" topic.
Thus revealing the plugin's topic brings the plugin configuration options
in sight within the "Page Panel".

Todo:
- Make Workspace Assignment of end-user count to the workspace-topic assigned
to the most current "Sign-up Configuration" topic.
- Make all templates use this new configuration.

A "Sign-up Configuration" becomes current after assignment to the (green)
"DeepaMehta 4 Sign up" Plugin Topic and after restart of the bundle/platform.

Note:
There must be just one Association (with Role Type: Default) between the
"Sign-up Configuration" and the "DeepaMehta 4 Sign up" Topic at one time.
