Improve FileCopier

This endeavor started out quite innocently: fix the connect syntax in
ProgressDialog, but it quickly became much more. Vom Höxchen aufs
Stöxchen :)

First I thought it would be nice to add a total count to the
ProgressDialog. Then I realized that I had QElapsedTimer::restart()
totally wrong. It returns the ms *since the last restart*! It doesn't
reset to zero, so fix that.

While testing that I noticed that the download speed was quite below
average, so change the buffer size and only check if we were cancelled
when the timer elapsed. But that wasn't it. Eventually I dug into my
firewall rules and routings to get it right.
