Subject: [PATCH] license: Fixing the license file to be correctly scooped up
 by Github automation

Renamed COPYING.txt to LICENSE.txt, and ensured the copyright year
is the first line in the license file. This causes GitHub to correctly
identify the zlib license and report it on SDL's project page.
