CQS: multiple-choice & true/false

Closes CNVS-15053, CNVS-13442

TEST PLAN
---- ----

  - create a quiz with multiple choice and T/F questions
    - take it by a number of students (tip: you can use Quizard to do
      this)
  - go to /courses/:id/quizzes/:id/statistics_cqs (CQS)
  - in another tab, open /courses/:id/quizzes#/:id/statistics (ember)
  - compare the functionality between the original Ember page and the
    new one regarding the question boxes for the questions, as described
    in the ticket
    + pay special attention to tooltips and dialog functionality
  - this patch also fixes the translation issue we had described here:
    https://instructure.atlassian.net/browse/CNVS-13442

what not to test:

  - toggling of answer drilldown/details, coming later in CNVS-15054
