Unstyle list of exams in child material listings

* Unstyle child exam list in the course materials items display
  (fixes #1651)
get_live_datetime handles missing ready mode item

* When course_materials.get_live_datetime gets a thing that has no ready
  mode, it helpfully returns a bit of HTML that can be used to tell the
  user this.
  (closes #1600)
ContentGroups handle deletion of target items

* Fixes display bug causing deleted child items to be displayed in live
  mode (fixes #1652)
* Fixes semantic bug causing item deletion to leave vestigial
  ContentGroup entries. New semantic introduced for parent/child
  deletion:
  - Deletion of the target object also deletes its ContentGroup entry
  - Furthermore, if the target object is a ContentGroup parent, its
    related ContentGroup children are promoted to be parents.
  (fixes #1481)
