Fixed to work with current feedparser API

rsj wasn't working with the new feedparser API and as the package.json didn't lock the feedparser version to the old one the whole module was no longer working.

- Updated the module code to work with the new feedparser version
- Removed node_modules completely.  
  Because reusable packages shouldn't check in their dependencies.  
  That's what package.json is for.
- Cleaned up dependencies in package.json
