Stable release 2013-10-25

Breaking changes

• on-* event handlers will now use data binding to function, requiring "{{" and "}}" around the handler name
  Example: <input on-focus="{{ focus }}" on-blur="{{ blur }}" on-change="{{ change }}">. This enables non-bubbling events, and makes for a much simpler event handling paradigm
• The timing of the created() callback is now at the Custom Elements createdCallback() time. Before, it ShadowDOM creation time. Use "ready()" instead to know when an element has its bindings, Shadow DOM has been created, and it's on-* handlers and property observers have been setup. This is to match the CustomElements spec.
• enteredDocument and leftDocument are removed. Use enteredView() and leftView(). These have been deprecated by the CustomElements spec, with the new callbacks available since 0.0.20130912
