Travis Ralston 17656e8cf7 Implement basic postMessage widget API components
This implements a 'screenshot' button on the generic widget wrapper, although there's several bugs with the current Riot implementation that prevent it from working and that is why it is commented out.

Fixes #155. Even if it doesn't work.
