Project: mediawiki/extensions/GettingStarted  aba693a597087ee3c42a97356a1613aaaf6a885b

Remove uses of Special:GettingStarted from task toolbar

* Remove now-unneeded dependencies
* Don't put everything in doc ready, so AJAX request can kick off before it.
* Tweak CSS to accomodate removed 'back to list'
* If AJAX request fails, try again when they click.  If it still fails,
  notify them at that point.
