Bug#698832: Wikipedia logo

[Martijn Hoekstra]

I just stumbled across this bug, and would like to note that the wikipedia
logo is a trademark of the Wikipedia Foundation. I think (though I'm not
sure) that that means the logo might have to be removed. Some relevant
trademark licensing policy of the WMF is located at
http://wikimediafoundation.org/wiki/Trademark_policy#Linking (as I assume
the logo is used on a button to link to wikipedia).
