Bug 844:
All enrollment pages (classlist upload, enroll single student, and
modify single student) now use the new date_setter which lets you set the
date right in the page.
The date setters respect the course default start and end dates.
An instructor can set the dates he/she/it chooses as the default for future
enrollments.
Added a 'no ending date' checkbox so the person enrolling can hit it instead
of setting the date to Dec 31st, 1969, 7pm or whatever the unixtime start
date is for their time zone.
