really fixing view-configs of types, changes to model part 1.

Fixes:
- finally "resources" and "tags" now show up in the "Create"-Menu of dm4-webclient
- our app logs all test-users in so contents remain editable in dm4-webclient
- fixed badly written upvote/dowvote-implementation
- simplified tag creation process on client-side/app-cache (now part adding new resource)

Features:
- a resource detail view is now to mainly divided into
  first 'show info', then possibly 'edit info' and does not ship a 'delete' command anymore

Pending:
- allow users to manipulate the tag-filter per item
- enable users to edit and delete tags in single-resource/detail view
- consolidate timestamps on application level

Administrative:
- depends on the latest commit in the dm4.reviews-plugin

Testing continues.
