https:// links instead of http://

Hello,
I’m fixing mixed content errors on several sites, and going through plugins and themes to figure out where they come from. I saw a lot of http:// links in your plugin (most probably irrelevant, but could be https anyway), like:
http://en.wikipedia.org/wiki/Stop_words

Home

If you could change those to https wherever possible, that would be great.
Thanks
Nils
