Centralized Update status

I wanted to do this, so I created a modified version of the update module that shows everything installed, not just enabled modules.

I copied Drupal's update module folder (from the public_html/modules director) into a modules folder under the default site (sites/default/modules/update). I probably should have done some renaming, but I was in a bit of a hurry. My default site in my multi-site installation is a placeholder site, so I don't really have any content there, just a generic notice you probably aren't where you want to be. I have multisite info installed there too.

In the file update.compare.inc, at line 70 I commented out the skip disabled modules code.

	/* process everything, disabled or not
    elseif (empty($file->status)) {
      // Skip disabled modules or themes.
      continue;
    }
	*/
