Bug Fixes in KDE Base
Remove workaround to draw the focus indicator manually
In Oxygen the focus-indicator has only been drawn for widget
instances derived from QAbstractItemView and Q3ListView, so it
was not possible in Dolphin to use the style for drawing.
This has been fixed now in Oxygen, so using the style works now.
The custom code for drawing the text background will be removed
and replaced by a style-code later.
