Ao3 Reader 0.1.1

Not a huge release, feature/bugfix-wise (though there's a few!), but lots of nice backend cleanup, and I'm trying to be more organized about documenting changes and whatnot, so we've got a fancy github release page this time! The zip file attached to that should be unzipped into an existing ao3-reader install folder - I will see about getting a new OCP package built and added to that, but I really want to automate the process a bit more.

Many thanks to shootthelightsout, qwertynerd97, and diantox for contributing bug reports, QA, code and docs! I'm really excited that other people are interested in this project, which is very motivating :)
