Move most of the logic to handle the various Qt drop event types from QtFrame to QtDropTarget. This will allow reusing the logic in an upcoming commit implementing QtInstanceWidget::get_drop_target. The order in QtFrame::handleDrop slightly changes as the drag source is now notified after the QEvent has been accepted, but that shouldn't be relevant. No change in behavior expected or seen in a quick test of dragging and dropping text from Kate or Gedit to Writer and vice versa or between two Writer windows.
