Update MediaWiki Version

[DrewUniverse]

Our MediaWiki version is out of date. To determine exactly which release to upgrade to, our current version must be checked. Secondly, there are specific PHP requirements that slowly increase with major releases, so Drew will need to check what version of PHP is possible on our web server before we commit to a specific new release.
