moodle/course/edit.php
mjollnir_ 0705ff843b Course request feature. Allows normal users to 'request' courses they would like created,
and admins can approve or reject pending courses.

Also, contains the ability to restrict activity modules on a per course basic. Strict config options:
  enable restricting modules at ALL (for all courses, no courses, requested courses), what to do by default for newly created courses
  as well as what modules to enable for above category by default.

This feature was created for the aim of building a community side to moodle - for institutes that have strict courses and enrolments, allowing normal users to request interest courses is a good feature,
but some modules may be redundant (assignment, lesson, quiz etc)

  Please test!
