Should also save some ram but didn't notice any changes there
* Dolphin windows still have a window icon
* Doing "open containing folder" in an app for the first time feels quicker
(imho the "daemon" should quit after having fullfilled the dbus activation request but that's an unrelated issue)
The plasma-integration platform theme still creates a `KIconLoader`, so this is probably moot. :/ If we could/would use `QCommandLineParser` before creating the `QApplication` we could set `desktopSettingsAware` to `false` to prevent all of this
