big fix for Subscenter

they changed their web so the old script no longer works.
i also changed the way the subtitles are displayed so it will be sorted by their rating (how close the file name to the rls name)
another update on the site

they changed back to subscenter.org
also small bug fix
messed up the credits by mistake

sorry for that...
