The entries in the QuickLaunchWidget are now saved properly. This means
that the format with which they are saved needed to be changed, since we
now also need to store the order of the entries. To do this, the entries
are now saved using the following value format: "<index>:<path>". When
loading, we simply parse this structure out and sort by the index,
before parsing the path into `QuickLaunchEntry`s.
System Monitor can already be accessed quickly by clicking one of the
resource graph applets in the task bar, so this icon was redundant.
Assistant can be opened with the Super+Space hotkey, so we don't need a
dedicated icon for it.
