[Web Apps] The Django-based application is now fully functional.

Note that several important issues remain to be fixed:
1. Enable log (in WSGI mode).
2. Replace the hard-coded path of the OpenTrep library within views.py
   See #3 below.
3. Adapt the CMake project so that the Django-based Web application
   be installed. It should solve #2 as well.
