Twenty Thirteen: improve backward compatibility escape hatch for pre-3.6 versions:

Browse Source 
* Switch to the built-in method of providing a back link in `wp_die()` for the Customizer
 * Use WP_DEFAULT_THEME for both arguments during theme switching to simplify the logic
 * Prevent the 3.3 and earlier theme preview action gracefully

Props obenland for patches, fixes #24441.
