New checks and updates from Frank Klein at Automattic. Thanks Frank! 

* Updated deprecated function listings
* Customizer check: All add_settings must use sanitization callbacks, for security
* Plugin territory checks: Themes must not register post types or taxonomies or add shortcodes for post content
* Widgets: Calls to register_sidebar must be called from the widgets_init action hook
* Title: <title> tags must exist and not have anything in them other than a call to wp_title()
* CDN: Checks for use of common CDNs
* Note: Changed plugin and author URIs due to old URIs being invalid. These may change again in the future, the URIs to my own site are temporarily only.
