* issue: the updated date might be a little off by the nature of the job queue.

* patch 2 trailing corrections.

* patch 3 abandon

* patch 4 corrections to patch 3

* patch 5 adjustments and corrections

* patch 6 $wgScript usage change on SpecialOWDownloads.php

* patch 7 deleted unused functions and moved csv function to its own
          script

* patch 8 added definition csv job generator. Using a job that creates
	  other jobs until the whole file is generated. A way to escape
	  the randomness of job execution. Drawback is that it takes a
	  lot of page activity to finish... unless used with runJobs.php

* patch 9 (Kip) still learning some php... apparently we don't need to
define "global" if not inside a function (amended WikiDataGlobals.php).
