Add Swedish language
I've begun translating the interface into Swedish in Transifex. I've managed to translate most of the -core-package now (24 strings remaining), and expect to be somewhat done by tomorrow. I'd therefore like the language to be added to the official language list.
I guess that adding the language to the arrays in function get_languages() in includes/functions.inc would suffice.
Swedish/Svenska
Language code either "sv" or "sv_SE".
