Make All Loggers table more readable / informational

[alythobani]

Right now the associated user and question for each Logger are being displayed as their respective MongoDB ObjectIds which are not very human readable.

We ideally want to also display:

• the user's CWL id
• the user's section and term
• the name of the question
• the name of the lesson

[alythobani]

Currently the Loggers table is displayed using information from a list of Logger objects, which only have a question ID and user ID attached to them. To avoid doing a lot of mongodb calls (one for each user, one for each question, one for each question's lesson) it looks like the package mongo-join-query might be useful.

After looking more into it, looks like we'll be better off using the functions in BitFit/client/src/actions/index.js.
