Update XML tags and SE website in Slovenian language file.

Version number not yet changed.  More than 70 new translations have to be added.  It might take some time!

Please leave this as it was for consistency; it's not a clickable link and the `http://` part is redundant. Even the `www` part is redundant but I'll leave that for another patch which will change it everywhere.
