This Fixes #1040 : Added new settings option for diplaying terse date sin notebooks kistory. Based on the selected option the terse dates will be displayed elase all dates will be shown
This Fixes #1040 : Removing the unused function
don't have "terse dates" control years; always show dates for notebooks

.. as opposed to versions, where the date is controlled by "terse dates"

are shown; I think that's unrelated.  So I'm reverting that part and only
applying "terse dates" for versions.
