Lacking 'sources' in package.yml

[afoeder]

David, the package.yml has no sources defined, I'd love if you could extend them:

      - "Source/LightFace.js"
      - "Source/LightFace.Image.js"
      - "Source/LightFace.IFrame.js"
      - "Source/LightFace.Static.js"
      - "Source/LightFace.Request.js"
