upgrade FCKeditor from 2.6.4 to 2.6.4.1 (security update, see comments below) The security issue fixed in 2.6.4.1 had no relevance to the FCKeditor features used by MoinMoin. Thus we were not in a hurry to incorporate this and push out a new moin release with it. But as a new moin release is pending now anyway, we include the latest FCKeditor release now anyway, just to have everything up-to-date. :)
