commit b2ebb4fb87f5a37cade7a6bfb889e59697c772a4
Author: Mohammad Akhlaghi <mohammad@akhlaghi.org>

NEWS: cleaner formatting, adding names
Until now, the NEWS file had two problems: 1) multiple items were placed at
the immediate next line which made it look like a long and hard to read
paragraph. 2) When a new feature or bug was specifically written or
directly suggested with the help of someone, that person's name wasn't
mentioned.
With this commit, both issues are fixed: when there are multiple items
under each other, an empty line is inserted, and when a step was written by
someone or directly suggested/influenced by someone their name is added. I
may have missed some people now, but will hopefully find/fix them before
the next release.
Adding the names of people who contributed was inspired by WCSLIB's
'CHANGES' file: https://www.atnf.csiro.au/people/mcalabre/WCS/CHANGES
