Speed up file copy

Hmm, as it turns out QFile does a much better, e.g. faster, job than my
open-coded file copy with a progress dialog.

I always wondered why it only did 150-170Mbit. I thought that it was
just the calculation, but now I have 400 Mbit, and it still stalls at
150 Mbit.

QFile::copy maxes out the line, so get rid of the ProgressDialog and
show a status message instead.

Copy can be canceled by the context menu, but FileCopier will always
finish the current file, because I don't want to lock and unlock the
CancelMutex during copy. Besides, QFile::copy doesn't admit that :)
