Ww3 feature/login status

Adds the login status to classlist manager.  This shows up as username in bold italics and darkgreen (editable via css)
Changes the email in the classlist manager to save space much like a recent ww2 change. 

Note: this depends on the ww3-feature/table-size and ww3-feature/back-button branches.  Those should be pulled first.

To test:
1. go to the classlist manager. 
2. You should notice the change in email view immediately and the username for your user should be in a different format. 
3. Also, if you can use a different browser, login to the course as a different user.  Within 30 seconds, the classlist view should show that that user is now active (logged in).
