Changed attendance to string in performance with functions to convert it to dict
Added attendance links to module view, trying around with fixed table header for attendance
Moved helptext and option buttons for default sessions (module form) to the UNISETTINGS file, generating HTML in the forms.py and JQuery code in the views.py. Not beautiful, but it works
Added all teaching weeks function to module class
Finally happy with attendance template, now to writing tests and form handling
