    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.
