update wikipedia video-editing comparison page to include Kd

the current page makes small mention of Kino, but nothing of kdenlive:

http://en.wikipedia.org/wiki/Comparison ... g_software

might be a good way to raise the profile of kdenlive

sadly, i don't know enough about digi-vid-ed to update the page.

regards

i see someone has updated both pages, cheers whoever it was.
