Major update because this switches to Prettier (https://prettier.io/) for JS source formatting.

While Prettier doesn't exactly match our previous style (and furthermore is quite opinionated and with limited configurability), it will produce very consistent results with a low error rate. This is due to two factors: one is its pervasive use within the JS community means that most bugs have already been flushed out; the other is because it is really just an AST printer, which means that it isn't prone to the bugs we've seen in our own regex-based source formatter.
