CVS tags: version_1_2_X, version_1_2_99_0, version_1_2_1, version_1_2_0, version_1_1_99_5, version_1_1_99_4, version_1_1_99_3, version_1_1_99_2, version_1_1_99_1, HEAD
Calls to functions in localenroll.pm mediated by lonc/lond now include domain
in the set of passed parameters to support domain-specific variants in a single
localenroll.pm file housed on a multi-domain library server.

Automated enrollment now sets first access and last access dates for student
roles based on defaults set on course creation, and modifiable via a number
of mechanisms in the Enrollment Manager, and Automated Enrollment Manager.

The Automated Enrollment Manager now provides a utility to allow enrollment type
to be toggled between 'auto' and 'manual', so that students added via CSV file
or singly can become liable for automated update (dropping, section switching
etc.).
