Make 'events' explicit dependency

[relativityboy]

The npm package events is used in /src/api/index.js but isn't named as a dependency in package.json

I'm getting this issue too

[bnchdrff]

this is in node core right?

[bnchdrff]

(not in browsers though, duh)

The event's package is in node core and should be injected by webpack. What is the specific issue you're having?
