Publish-subscribe functionality

Demo and API docs

##<iron-signals>

iron-signals provides basic publish-subscribe functionality.

Note: avoid using iron-signals whenever you can use a controller (parent element) to mediate communication instead.

To send a signal, fire a custom event of type iron-signal, with a detail object containing name and data fields.

this.fire('iron-signal', {name: 'hello', data: null});

To receive a signal, listen for iron-signal-<name> event on a iron-signals element.

You can fire a signal event from anywhere, and all iron-signals elements will receive the event, regardless of where they are in DOM.
