Implement Drag and Drop in Movie Archive

Well, this was actually a bit of a drag. You have read the docs very
carefully to get it right. For one, don't construct the drag object in
mousePressEvent if you also want a double click, otherwise you end up
with very weird behavior.

Same goes for the receiving end. Differentiate between dragEnterEvent
and dragMoveEvent, otherwise you'll only be able to drop items if you
hit the right row on entering.

There are some artefacts during the drag, but I guess that's a Qt bug.
Didn't bother to look into it.
