"batch propieties edition"

I was trying to make an stopmotion clip with photos and I wan unable to find the way to change the duration time of the images in batch, I had to change the duration of all stills one by one... it could be usefull if you could change propeties or effects in batch... sorry if it is possible with the actual relase but I cant do that...

Ok, I just added that feature in svn (rev. 4133), will be in the next Kdenlive release that should hopefully be out in the first days of february.
