The teacher can now view all the discussion posts for the current period selected (specific periods, or all periods). I didn't implement the interactions within this view (see below for details).
How to test:
Open the grading tool, and go to grade-by-step view
Open a discussion component for a particular workgroup.
Under all the posts that the workgroup has done, there is a link to "See entire class discussion". Click on the link. This should open a popup
Test that:
you can see all of the students' posts for the current period (the current period should match the period selection drop-down).
you can sort by latest, oldest, most-votes, and least votes
other interactions (deleting, undeleting, voting posts) are not enabled in the popup for now. I think we should refactor the code a bit before adding those functionalities. You can still perform those functions in the original grade-by-workgroup view for each workgroup.
you can close the popup by hitting escape, or clicking on the close button or outside the popup window.
