* Causes the Manage Themes page to refresh if the customizer is closed after the active theme is switched. * Changes the text of the 'Save and Activate' button once the theme has been activated. * Improves the naming of the customize control settings. * Add events to customize.Loader and make callbacks more flexible. * Makes the customize-loader l10n compatible with non-admin settings. * Adds WP_Customize->is_current_theme_active(). * Minor style corrections, including jQuery.attr/prop changes. git-svn-id: http://core.svn.wordpress.org/trunk@20802 1a063a9b-81f0-0310-95a4-ce76da25c4cd
