[PATCH v4 3/9] templatetags: add utils template filters and tags

[Raxel Gutierrez]

Add utils.py file to create template filters and tags that can be used
by most if not all objects in Patchwork. In particular, add a template
filter to get the plural verbose name of a model and add a template tag
that returns whether an object is editable by the current user. These
utilities will be used in an upcoming patch that adds the `addressed`
status label to patch and cover comments.
