<h3>Log Message</h3>
<pre>Theme Customizer: Properly change state when theme is switched. fixes <a href="http://core.trac.wordpress.org/ticket/20610">#20610</a>, see <a href="http://core.trac.wordpress.org/ticket/19910">#19910</a>.
* 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.</pre>
