The interaction of Qt's drag & drop with GroupedLineEdit was exceedingly weird. The user was able to scroll the viewport making the text invisible. This implements a very primitive alternative drag & drop functionality: dropped text is regarged as a distinct tag. This means that it is not possible to modify existing tags by dropping in the middle of them. Arguably, this might even be better than arbitrary drag & drop. But even if not perfect, this fixes a very nasty UI behavior. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
