The default of 32 px should be fine in most cases and when the UI is scaled
it is also automatically scaled. However, if one has a tray area or Plasma
panel with extraordinarily big icons like latte-dock it might still be
required to render icons at a higher resolution. This is hard to determine
programmatically so I'm just adding a manual setting.
The external inotify tool is likely not used anymore. It makes sense to
keep the concept of supporting additional tools because it might be used
in the future again. So it seems best to give the additional launcher a
more generic name.
