Title: Update content/developers/addons/developing-widgets.md

as described in \system\cms\modules\widgets\libraries\Widgets.php with the method "prepare_options",
there is a hook to alter data before they are inserted in database.

The built-in rss_feed widget is using this method too ( even if it does nothing )
