What's the dist folder used for?

Currently, there's a dist npm script which generates a bunch of browser distributions into the dist folder. However, these builds don't appear to be referenced anywhere--the browser field in package.json doesn't include any files from the dist folder, and the dist folder isn't included in the version distributed to npm.

It was used originally to generate standalone library bundles which could be downloaded from GitHub. This isn't used anymore so likely safe to delete (done in #428).
