Utilize Wikipedia permalinks when used as ref/source

[todrobbins]

So as to provide more specificity and fixity in linking, I'd suggest that all Wikipedia page links utilize one of the Wikipedia permalink options:

A permanent link (or permalink) is a link to a specific version of a wiki page. Normal links always lead to the current version of a page, but the permalink leads to the text as it was at the time; the text does not include any edits made since. Unlike what the name suggests, the permalink does not show exactly the same page, though, only the main text is guaranteed to be retained. The pictures included in the page are still shown at their most current versions, as are the templates, most notably the boxes with text and images placed in the pages' right-top corner, as well as any content transcluded from other pages. In other words, the permalink displays what the article would look like today if someone reverted to the revision in question.

I'd be happy to go through existing refs and update them to permalinks.

Thoughts?

Can Wikidata be used instead?

[todrobbins]

@akuckartz Wikidata can definitely be used instead although I don't think all administrative units are anywhere near fully represented in Wikidata currently, hence the default to Wikipedia lists.

This is a dumb question, but which refs/links are you going to change? Just things in READMEs or am I missing somewhere that OCD is storing specific links?

[todrobbins]

@epaulson not a dumb question. I'm referring to all of the identifier README.md files (e.g. https://github.com/opencivicdata/ocd-division-ids/blob/master/identifiers/country-ar/README.md)
