[kde-edu]: www/media/includes/classes

[Ben Cooksley]

Just a quick note that it would have been much easier to solve this,
and much quicker if checking out www/sites/edu didn't take 1 hour and
11 minutes due to it being 660mb. This is primarily caused by Marble
and KStars as well as the old site. KLettres adds a bit too.

Regards,
Ben.
