Deprecated function split() / Strict Standards error

With define('WP_DEBUG', true); in wp-config.php some errors can be observed on settings page of WP Native Dashboard:

At each entry of installed languages:

Deprecated: Function split() is deprecated in …/wp-content/plugins/wp-native-dashboard/wp-native-dashboard.php on line 90

Strict Standards: Only variables should be passed by reference in …/wp-content/plugins/wp-native-dashboard/wp-native-dashboard.php on line 90

At downloads:

Deprecated: Function split() is deprecated in …/wp-content/plugins/wp-native-dashboard/wp-native-dashboard.php on line 547

File wp-native-dashboard.php:

Suggested fix 1: Use explode() instead of split() in line 90 and 547, see also http://www.php.net/manual/en/function.split.php

This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.

Suggested fix 2, line 90, currect version:

function wp_native_dashboard_is_rtl_language($locale) {
	$rtl = array('ar', 'ckb', 'fa', 'he', 'ur', 'ug');
	return in_array(array_shift(split('_',$locale)), $rtl);
}

Changed version, array_shift ( array &$array ) requires a variable by reference instead of just a function result:

function wp_native_dashboard_is_rtl_language($locale) {
	$rtl = array('ar', 'ckb', 'fa', 'he', 'ur', 'ug');
	$lang = explode('_',$locale);
	return in_array(array_shift($lang), $rtl);
}

Thanks for the great plugin.
