Add hook for after values saved in customizer

[dovyp]

Please add the following line to the the next release of WordPress.

do_action( 'customize_save_after', $this );
to line: 514 of class-wp-customize-manager.php

The full function should look as follows:

	public function save() {
		if ( ! $this->is_preview() )
			die;

		check_ajax_referer( 'save-customize_' . $this->get_stylesheet(), 'nonce' );

		// Do we have to switch themes?
		if ( ! $this->is_theme_active() ) {
			// Temporarily stop previewing the theme to allow switch_themes()
			// to operate properly.
			$this->stop_previewing_theme();
			switch_theme( $this->get_stylesheet() );
			$this->start_previewing_theme();
		}

		do_action( 'customize_save', $this );

		foreach ( $this->settings as $setting ) {
			$setting->save();
		}
		do_action( 'customize_save_after', $this );
		die;
	}

This will allow us to use a hook for after the settings from the customizer have been saved.

Seems like an oversight, and I absolutely see where it would be useful. "after" hooks are a common pattern for us.
