kcms/baloo: Open row's directory on click
See utilities/filelight!106 (merged)
This is a bad implementation of a good idea, I'd say. Delegate highlight messes up with legibility of its ComboBox, and opening directories is arguably not the most prominent task user would open this KCM for. There should be a way to interact with those special-cased directories, just a more subtle one. Maybe a click on an icon?
