Component.json

This is the component.json for [Ticket 14644](http://bugs.jquery.com/ticket/14664).

This branch is branched from 2.1.0-rc1 as requested. I've tested this locally and other Component dependencies are able to locate jQuery.

Just having a component.json on master won't work tho. A tag must exist for the version contained in the "version" for Component to be able to fetch, much like Bower.

Let me know when you tag 2.1.0-rc2 so I can test this.

BTW, can we also get this for the 1.x branch?
