Changes

The Wikipedia project underwent a [https://en.wikipedia.org/wiki/GNU_Free_Documentation_License licensing update ] in 2008/2009 from [https://gnu.org/licenses/fdl.html GFDL ] to dual-licensing scheme including the non-compatible [https://creativecommons.org/licenses/by-sa/3.0/ CC-BY-SA].  In 2016, I'm noticing that there are some quirks in the software that I'm still investigating, so I've got notes here. Basically, I want to simply figure out whether there are any issues to implementors / site Administrators. '''When setting up a fresh install of MediaWiki; or upgrading a previous installation; is there anything to do with regard to the licensing templates or interface messages so that [[Special:Upload]] "just works"?''' One oddity that I found was that there were a bunch of "self-published" options available in the licensing dropdown, however they rely on a template named 'self' which was not present in this wiki. It is not a trivial exercise to export/import the template from mediawiki.org nor wikipedia.com. Because of the complex nature of these licensing templates, it is not possible to "copy" the template text.
