Minor release of my uploader, with some essential upgrades, unit tests, and a complete redesign.

Still just a minor release because I will be adding wikis and long-form article processing, as well as folder-based 30040 structures, and some other stuff, and that'll be the 0.2 release. Everything I'll need to produce test data for #Alexandria's Gutenberg edition.

Inching my way there.
