feat(Dialog Guidance): Summary display for teachers

[Aaron-Detre]

Changes

• Added a teacher summary display for Dialog Guidance components that shows the ideas that the most students detected in the section.

Test

• Teacher Tools > Grade by step > Dialog Guidance component > Step info
• Make sure you can see the top 3 ideas detected (ordered from most common to least common) and the bottom 3 ideas detected (ordered from least common to most common).
• Make sure the "see all ideas" link shows the all ideas section (ordered based on id).
• Make sure the "hide all ideas" link hides the all ideas section.
• Make sure that if no ideas have been detected, a message saying that ideas will show up here is displayed.

Closes #2094

Functionality works as described.

As we discussed today, let's change this component so that instead of showing just the "Most common ideas", we would

• show "Most common ideas" (shows top 3)
• show "Least common ideas" (shows top 3)
• show a link to "Show all ideas" (when clicked, shows all ideas in the rubric and their count)

Don't show any of the above if no ideas were detected by any of the students.

Also:

• add unit tests
• see inline comments for code improvement suggestions

New changes look good. 👍

I added code improvement suggestions on new code (and some older code that I had missed before).

Add i18n tags to elements and generate messages, and remember to add tests.

LGTM. 👍

Can you do these before merge:

1. Change fdescribe to describe
2. Remove unused Config import in spec file
3. Merge develop and regenerate messages. This should resolve the conflict
4. Wait for @breity to review and style
