Subject: [PATCH] Fix bug when using Mediawiki Installer.

fix the following message error :
Fatal error:  Call to undefined function wfWaitForSlaves() in maintenance/populateCategory.inc on line 66

This wfWaitForSlaves() function exists only in commandLine.inc but updater can't call it when not using command line tool.
Adding this function in the end of populateCategory.inc.
