Bug 5176 Tracking enrollment changes.
lonuserutils
- $context passed as an additional arg to a number of routines so it propagates to lonnet::modify_student_enrollment() and lonnet::assignrole()
loncreateuser
- &print_userchangelogs_display() displays role change history in a course
- &role_display_filter() and &rolechg_contexts() used by print_userchangelogs()
- View Login History and View Change Logs added to User Management main menu
Work in progress.
