/**
 * This module still needs a lot of work, but is functional today.
 * Please review this section if you upgrade because things will change.
 * If you have issues upgrading, remove facebook from the addon list, 
 * view a page on your site, then add it back to the list. This will reset
 * all of the plugin 'hooks'. 
 *
 * 1. register an API key for your site from developer.facebook.com
 *   a. We'd be very happy if you include "Friendika" in the application name
 *      to increase name recognition. The Friendika icons are also present
 *      in the images directory and may be uploaded as a Facebook app icon.
 *      Use images/ff-16.jpg for the Icon and images/ff-128.jpg for the Logo.
 *   b. The url should be your site URL with a trailing slash.
 *      You may use http://portal.friendika.com/privacy as the privacy policy
 *      URL unless your site has different requirements, and 
 *      http://portal.friendika.com as the Terms of Service URL unless
 *      you have different requirements. (Friendika is a software application
 *      and does not require Terms of Service, though your installation of it might).
 *   c. Set the following values in your .htconfig.php file
 *         $a->config['facebook']['appid'] = 'xxxxxxxxxxx';
 *         $a->config['facebook']['appsecret'] = 'xxxxxxxxxxxxxxx';
 *      Replace with the settings Facebook gives you.
 * 2. Enable the facebook plugin by including it in .htconfig.php - e.g. 
 *     $a->config['system']['addon'] = 'plugin1,plugin2,facebook';
 * 3. Visit your site url + '/facebook' (e.g. http://example.com/facebook)
 *    and click 'Install Facebook posting'.
 * 4. This will ask you to login to Facebook and grant permission to the 
 *    plugin to do its stuff. Allow it to do so. 
 * 5. You're done. To turn it off visit your site's /facebook page again and
 *    'Remove Facebook posting'.
 *
 * Turn logging on (see the github Friendika wiki page 'Settings') and 
 * repeat these steps if you have trouble.
 * Vidoes and embeds will not be posted if there is no other content. Links 
 * and images will be converted to text and long posts truncated - with a link
 * to view the full post. Posts with permission settings and comments will
 * not be posted to Facebook. 
 *
