Integration with Meteor.js - http://meteor.com

Hey @sporritt,

I'm a Meteor.js dev and volunteer package maintainer for [Meteor](http://meteor.com). We had a wrapper package for jsPlumb that was [difficult to maintain](https://github.com/udondan/meteor-jsPlump/issues/), and thought it'd be best if the integration comes straight from the source - hence this PR.

This PR will allow you to directly publish updated versions of the library as they become available. All you have to do is create an account at https://meteor.com/ (click *SIGN IN*, then *Create account*). After you've done that, please let me know the name of the account, and I'll add you as a maintainer.

I've already published the current version of the package on [Atmosphere](https://atmospherejs.com/jsplumb/jsplumb) (Meteor's package directory). When you release new versions, you'll be able to publish them to Atmosphere by running `meteor/publish.sh`.

Thanks & best regards,
Dan
