Updating to match popular styleguide

[shrugs]

I've adopted the airbnb style guide, enforced via eslint, for all of my projects, which means the semicolons are getting annoying to remove and trailing commas need to be added for snippets like rncc.

My currently plan is to bump the major version number so that clients shouldn't automatically update to the new version. Timeline for this isn't determined, but it will be "soon".

Just making an issue for those watching the repository to be informed.
