Added support for making multiple changes in a single commit, using the flask dict "session" (keys used are "modified_categories" and "deleted_categories") + Added a view for editing categories that allows the user to see what he has added, deleted or edited + Made it so an unauthenticated user should not generate any Github api request (you have to be logged to see the categories now).
