/**
* Installing the Friendika/Facebook connector
*
* 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/friendika-16.jpg for the Icon and images/friendika-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 the Facebook Settings section of the "Settings->Plugin Settings" page.
* and click 'Install Facebook Connector'.
* 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 the Plugin Settings page again and
* 'Remove Facebook posting'.
*
* Vidoes and embeds will not be posted if there is no other content. Links
* and images will be converted to a format suitable for the Facebook API and
* long posts truncated - with a link to view the full post.
*
* Facebook contacts will not be able to view private photos, as they are not able to
* authenticate to your site to establish identity. We will address this
* in a future release.
