Cut a couple of files on my desktop, they got dimmed. If I copied something else they showed up again.
Also, cutting files from Dolphin updated FolderView right away.
I noticed that `KUrlMimeData::urlsFromMimeData` seems quite slow, when I cut an entire folder in Dolphin, even if it's one we don't show in a FolderView, it can lead to a noticeable (as in a second or two) hickup in Plasma :/
Code is adapted from Dolphin.
