Implicit NPM Dependency on Versionify

[deckar01]

Issue

package-json-versionify is used as a babel plugin, but is not declared as an npm dependency.

This worked locally, because it is a dependency of webtorrent and npm sometimes flattens the dependency tree, but other versions of npm and other environments may not.

Solution

Run npm install --save-dev package-json-versionify to add the dependency to package.json.
