WooCommerce detection problem on multisite

Hello,

The plugin did not activate because on my WordPress Multisite, WooCommerce is not site wide activated.
Here is the correct ic_is_woocommerce_active function (wworking for me) :

function ic_is_woocommerce_active() {
	$plugin_file = 'woocommerce/woocommerce.php';
	if ( in_array( $plugin_file, apply_filters( 'active_plugins', get_option( 'active_plugins' ) ) ) ) {
		return true;
	}
	if ( is_multisite() ) {
		$plugins = get_site_option( 'active_sitewide_plugins' );
		if ( isset( $plugins[ $plugin_file ] ) ) {
			return true;
		}
	}

	return false;
}

If you can add this modification, it will be great.
Thank you for your plugin.
