Minor rewording/clarifications in Witch-king document
16 Mar 2020
Fix reference of Second Age to be Third Age in the Witch-king
document (about the prophecy), something that felt wrong at the time
but was too tired for it to properly register. I have also added the
year this occurred.

New index with document on the Witch-king of Angmar and his fall
(today is the anniversary of his fall at the Pelennor Fields).
