Project: mediawiki/extensions/Parsoid  62479a1ca074f0752b386b059101c352de58bcce

Allow parsoid to be easily deployed to appfog.

For new contributors or third-party users, appfog.com can be an easy
way to deploy a parsoid instance.  To support this use, we:

* Bind server to proper port for AppFog deployment
* Add 'npm start' command (AppFog uses the 'start' script to figure out
  how to run our app.)
* Add a manifest.yml describing parsoid.
