Dragging and selection fixes

- Don't clear the selection on mouse-press events, do it (if
  allowed) in the mouse-release-event. Otherwise dragging of
  multiple selected items would not be possible.
- Don't clear the selection when the context-menu gets opened
  by a right-click.
- Fix issue that dragging is not possible after the first
  drop that has been canceled.
