Added missing "charset" definition. Also, while at it, corrected indentation of the <ol> and <ul> elements.

See following bug report for details: http://joomlacode.org/gf/project/joomla/tracker/?action=TrackerItemEdit&tracker_item_id=31724

I tested it on Joomla 1.5, but can't test it on the current version, because I don't use it. I'm going to add a test procedure to the above bug report, for someone to test this quickly.
