Include guidelines in menu

[nichtich]

Add a "guidelines" ("Richtlinien") entry to the menu with a link to general guidelines and a list of guidelines for configured combinations of vocabularies (and/or selected source/target vocabularies).

The configuration format could be extended to make fromScheme and targetScheme optional:

{
   "guidelines": [
    { "url": "http://link.to/general-guidelines" },
    { "fromScheme": { "uri": "http://bartoc.org/en/node/1940" },
      "prefLabel": { "en": "Mapping from Wikidata" }, "url": "..." }
    { ... },
  ]
}

Selecting a guideline would also select the given combination of fromScheme / toScheme, so this feature is also useful to provide a list of vocabulary-combinations to look at.

We have this shown with an icon in the MappingEditor but a list of guidelines should be shown in ConceptDetail. Inject the guidelines as field subjectOf of the concept scheme in fromScheme. Then show it in ConceptDetail with title "mapping guideline" as default.

I think you need to clarify this.

1. Why the need to inject the guidelines? Where do the guidelines come from? if they are configured or hardcoded, we can use that data directly. Or do you mean they will be part of BARTOC, so the data will come from the API?
2. Why only fromScheme? It feels like mapping TO a vocabulary is just as important or even more important.
3. Where would the "mapping guideline" in ConceptDetail be placed exactly? I still feel like MappingEditor would be a better place.
4. How would we deal with guidelines that specify how to map one specific vocabulary to another specific vocabulary, like RVK-BK? In this case, it would also make more sense to show it in MappingEditor, I think.
