nice­filelist – Pro­vide \list­files align­ment

The pack­age ex­tends long­name­filelist, keep­ing sep­a­rate columns for date, ver­sion and “cap­tion” (the cap­tion now sep­a­rately listed). Align­ment is not dis­turbed by short file name ex­ten­sions, such as “.fd”.
The pack­age is not com­pat­i­ble with long­name­filelist: users need to re-read the doc­u­men­ta­tion.
