    A Dictionary for user preference values.

    For non-existing keys, either a defaultValue (false),

    or the value from a defaultDictionary is returned.

    This will eventually keep track of ALL user preferences.

    For now, not all preferences are found here -

    (some of them are currently spread over the system - especially, in Class-Variables)

    - but this will change over time.

    If more prefs are added, think about adding a corresponding UI to the SystemSettingsDialog too.
