This commit adds a new chart at the end of a scored survey.
Previously, you could see your "Overall Performance", meaning what was your
percentage of correct/partially correct/incorrect/skipped answers for all
the survey scored questions.
Now, we added a new chart new to it that shows the percentage of
correct/partially correct/incorrect/skipped answers but for each section of the
survey.
This allows the user to see in which section(s) he did the most mistakes.
