Add local group/team stuff

[mdrie]

Information about the local groups should be found when following a link "über \<Localgroup Name>". Provide the content required to display this link and sub-page:

• [x] Add model class LocalGroup with
  • name / Name (max 100 characters)
  • website / Website (optional)
  • teaser / Teaser (plain text max 200 characters, optional)
  • description / Beschreibung (markdown, optional)
  • featured_image / Bild (optional)
• [x] Add foreign key from City to LocalGroup
• [x] Make all LocalGroup fields inline-editable in Admin page for City
• [x] Add "über \<Localgroup Name>" link or correctly set name in the link text.
• [x] Setup sub-page showing with
  • name as Heading
  • website appropriately placed somewhere
• [x] on larger screens next to each other two divs of equal size:
  • One with the teaser in bold face and the formatted description.
  • One with the featured_image
  • Below each other on smaller screens. (as done automatically by bootstrap / tabler)
• [ ] #238
  • description should contain
  • Ehrenamtliche, Aktuelle Zahl, Zur Verfügung stehende Zeit. (Ziel: Erwartungsmanagement)
  • Kontakt, Beteiligungsmöglichkeit, Suche nach Mitstreitern.
  • Datengrundlage: Welche Quellen? Wen interviewt? Als Geschichte erzählt. (Ziel: Credibility)
  • ggf. Hintergrund zum Klimaaktionsplan? Wie war unser Weg dahin? (Link auf allgemeine Erklärung: Was ist ein KAP?)

Historical record: The first ideas to this issue were developed in the Miro board like so:

It might or might not help to have a look at discussion in wechange rocketchat thread "Was braucht die Website?"

Some content mentioned here is more appropriate on localzero.net (e.g. in the FAQ) and may be linked from our page, some content belongs into the global sup-page "Das Projekt" (or "Über Uns"). Some stuff belongs in the sub-page linked from the "Restzeit" card.

The only remaining point is "Über \<Localgroup Name>" which also may contain information.

TODO: Provide info about which info goes where.

I pushed a first pull request #233

However, there are still things we should discuss:

1. Holger, do we not need to name a responsible person per team? I.e. someone who is responsible in terms of the "impressum"? At the moment there is only a general "impressum" which suggests that GermanZero was responsible for everything that is written on the website including blatant nonsense that might be added by a local team. I would not want that if I was GermanZero. Do we not need a special type of framing "Impressum" here + a kind of impressum for each city or at least the naming of a responsible person?
2. Besides a website, I suggest that we should take a contact email for each group as a separate field (which could be identical to a responsible person, see 1.)
3. The content required ("should contain") for the description field feels too much to me. A lot of this will already be written on the website that we can link. Duplicate info (website + here) will only be forgotten to be updated in the future, especially when it is detailed info like team members, time available etc.

@kleins05 I agree with all three points. The reason for the last item in the description was to have some place to put all the stuff in that ugly wireframe (see Historical Record). In order not to loose track of the wish to have a place for this information, I will enter a fresh issue. And another one for the impressum issue.
