Subject: Use QFontMetrics::height() instead of averageCharWidth()

QFontMetrics::averageCharWidth() is quite slow and does not work
well on fonts with broken characters. In the
usecases required by Dolphin QFontMetrics::height() is a better
and faster alternative to get a font-dependent minimum width.

Thanks go to Christoph Feck for this hint!
