Tim Hunt 4175a57038 MDL-45970 quiz editing: fix display of random questions.
The pass by reference meant the function was clobbering the variable in
the calling function. Once that was change, it was not strictly
necessary to rename the variable in the function, but I did anyway for
clarity.

Thanks to Rajesh Taneja for finding the problem, and identifying which
bit of code was broken. I really just made the patch.

ACTIVITY MODULES
----------------

These are main modules in Moodle, allowing various activities.


Each of these modules contains a number of expected components:

  mod_form.php: a form to setup/update a module instance

  version.php: defines some meta-info and provides upgrading code

  pix/icon.gif: a 16x16 icon for the module

  db/install.xml: an SQL dump of all the required db tables and data

  index.php: a page to list all instances in a course

  view.php: a page to view a particular instance

  lib.php: any/all functions defined by the module should be in here.
         constants should be defined using MODULENAME_xxxxxx
         functions should be defined using modulename_xxxxxx

         There are a number of standard functions:

         modulename_add_instance()
         modulename_update_instance()
         modulename_delete_instance()

         modulename_user_complete()
         modulename_user_outline()

         modulename_cron()

         modulename_print_recent_activity()
