This allows the Overview Custon range to be saved and resurvive a reloaded of OSCAR.

a New feature has been been added but can not be activated until a UI file is changed - another submission.
This new feature will utilize the current displayed range as the custom range.
Other wise the Overview custom range uses the values from the calendar.
This changes does not require and data or translations.
