Allow users to create selections from Wikipedia books

[audiodude]

Fixes #644.

Users can create selections based on a Wikipedia "book" url, such as https://en.wikipedia.org/wiki/User:Audiodude/Books/test. The Book Builder fetches the wikitext of the page that is saved by this tool and parses out the article names, then saves them in S3. A frontend is provided for creation of Book selections, which verifies that the URL is present, valid, and matches the project selected in the dropdown.

Book selections can be used to create ZIM files just like any other selection.

@audiodude Does it grab title and subtitle?

@audiodude Does it grab title and subtitle?

It does not. I didn't see that requirement in the bug. What would you expect to use this data for? Selections currently only store their article lists (in S3) and don't have fields for additional metadata. I assume you want to use title and subtitle for metadata in the ZIM?

[kelson42]

@audiodude yes yes yes

[audiodude]

Okay I think we should create a separate bug to track that work, since it is substantially more complicated than what's in this PR and would bloat this one (which is, of course, already finished).

[audiodude]

I'm thinking of something following from #640 as well, where we can surface more of the ZIM metadata on the ZIM page, under an optional expanding section, with some of it pre-populated based on the result of the selection materialization.
