WP-AppKit: allow embeds (notably iframes) in apps

wpak-allow-all-embeds-in-apps

<?php
/*
 * Applies to:  since WP-AppKit 0.1
 * Goal:        By default, embeds are stripped from post content when send to WP-AppKit apps.
 *              We'd like to display embeds in apps (such as YouTube, Vimeo, SlideShare...).
 * Usage:       In the app's theme PHP folder or a separate plugin.
