desktop: overwrite drag & drop in TagWidget

Browse source 
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.
