if domains have spaces then it gets missed - fix included

I found by accident that if you put spaces between the comma in the domain input field then the space causes a failed comparison in the code and thus is not triggered.

In the function locale_language_multidomain()

Old code:

        $hosts = array();
        foreach (explode(',', $language->domain) as $host) {

New code:

        $hosts = array();
        $domainListStr = $language->domain;
        $domainListStr = str_ireplace(" ", "", $domainListStr);  //remove spaces
        foreach (explode(',', $domainListStr) as $host) {
