    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.

    (which are currently spread over the system).

    For now, only a few preferences are found here - but this

    will change over time.
