[PATCH v3 1/5] static: add JS Cookie Library to get csrftoken for fetch requests

[Raxel Gutierrez]

Currently, requests are made only through form submission and the
csrftoken is added to templates using {% csrf_token %}. Following Django
docs [1], the library is useful to add csrftoken when making requests in
JavaScript.
