Implement expand and collapse for DB view

Sounds easy, right? It is, if you don't try to create a QIcon from a
QChar. That took me a while...

First, it's not a good idea to fill the QPixmap for the QIcon with
transparency. That gives you a random background. Fill it with palette
color instead.

Then there's QFont's pixelSize(). I have absolutely no idea how it
corresponds to the pixmap's size, but roughly double the width of the
pixmap is a good guess...
