Add chunking for API requests

Fixes #60, hopefully.

Sadly, Wikimedia is still on ES6 as part of the compatibility policy, and because the gadget minifier is a dinosaur. Async/await is not supported. Can this patch please be refactored to remove await?

Sure, done.

It seems my patch would incidentally fix another, very similar bug:

Caused by

(the URL in question is this).

Oops, didn't realise the linter was that strict. I've fixed that as well.

@NovemLinguae , any chance of this being reviewed?

I'd have to get it running on testwiki, test it, then deploy it. Will see if I can make some time for that. Gotta refresh my memory, it's been awhile!

Looks hard to test too. Maybe I'll edit the code to have the chunks only be 2 big instead of 50 during the test. Then I can set up like 3 or 5 categories or something to test.

Okay, thanks for taking the time for this.
