EventEmitter2 dependency not specified in `package.json`

[goretkin]

The code depends on EventEmitter2 (e.g.

ros3djs/build/ros3d.js

Line 1313 in 2f2ae47

ROS3D.InteractiveMarkerHandle.prototype.__proto__ = EventEmitter2.prototype;

)

(roslibjs does specify the dependency and so it's included in the build: https://github.com/RobotWebTools/roslibjs/blob/e0d67d1fcd7f48b978ed00d059bf9d34ac6eec81/build/roslib.js#L3)

I see the dependency is specified in bower.js. Is this intentional?

Probably not. It is just uncaught dependency that nobody noticed. Would you create a PR to fix it? :)
