[MediaWiki-l] Installing the MediaWiki Math extension is easier now

In the past, administrators of MediaWiki installations faced a
challenging installation procedure when they tried to enable rendering
of mathematical formulae. As of February 22, no configuration or
custom installation is required with the latest versions of MediaWiki
core and the Math extension, if your wiki is connected to the
internet.

This is how it’s done:
For wikis connected to the internet: Simply download the latest
versions for both of Mediawiki core [1] and the Math extension [2] and
that's it. The latest version can be obtained by selecting “master” in
the extension distributor.

For wikis not connected to the internet:
Download the latest version of Mediawiki core [1] and the Math extension [2].
Install the node module mathoid [4]. We recommend using Node version 8
LTS [5], if node.js is not installed on the server. Mathoid can be
installed to any location of your server that is accessible to the web
server. For instance, in the location of the Math extension.
After having installed and tested (e.g., by running npm test) the
mathoid installation, point your MediaWiki to this location by adding
the following config to your LocalSettings.php file:

$wgMathoidCli = ['/srv/mathoid/cli.js', '-c', '/srv/mathoid/config.dev.yaml'];

Replace /srv/mathoid with the location of your mathoid installation
and run update.php [6].

If you have any issues with the installation, please file a
phabricator ticket using the following link
