Example of sending Bridgy Publish webmention

/**
 * This is an example of how I use Bridgy Publish.
 * This is for reference only, not necessarily the cleanest/best way to do this. :)
 * 
 * 1. When an admin views a note that isn't already syndicated to Twitter, display a Bridgy Publish button (not included in this file)
 * 2. When that form is submitted, use the module to send a Webmention to Bridgy Publish
 * 3. Decode and parse the JSON for the Twitter URL
 *
 * Note: my template has textarea field `syndication` for syndication URLs. I put the Bridgy Publish Twitter URL there and replace it with the tweet permalink after successful publishing.
