New/Edit calendar event page with section support

closes: #7978

test plan:
with cal2 enabled:
* click on event in calendar, hit edit, click "more options"
* you should be at a new page.
* it should have transferred any new description,
  start/end date you entered
* if it's for a course, you should see a checkbox
  "different due date per section", if it's on your own
   or a group cal, should not see that checkbox
* creating event should save properly so:
* verify that all events show up on calendar2
* when you go back to edit any of those events on
  calendar the info should all load on this page again
* when you click "edit" on one of the section events
  on the calendar it should let you edit the info for
  all of the sections not just the one you clicked on.

with calendar 2 disabled:
* make sure you can still create events as you used
 to be able to
