- Force python-ldap >= 3 to get proper bytes/string management.
- Replace common['name'] with common['first_name'] because the name is
  already broken by get_names. Actually, allauth breaks down
  common['name'] in 'first_name + last_name'.
- Decrease timeout of LDAP requests to 5s.
- Fix get_names in case the LDAP returned a string without any space
  character.
- Fix get_names in case the LDAP doesn't return any cn, which was
  failing with Py3.
- Add tests about populating user data from LDAP.

Remove CDN dependencies, copy files locally

Having requests to some CDNs on a login page is often considered Bad™,
since it can load third-party code on a sensitive page of the website.

As a side effect, this removes calls to fonts.google.com, which is a
known tracking website.

Qwann/small fixes

See merge request cof-geek/django-allauth-ens!1

Namely, it concerns the widgets: RadioSelect, CheckboxInput and Select.

- Update django-allauth-cas to the last version.
- Add docs (README, example/README).
- Add tests for Clipper provider.
- Add tests to check templates do not contain syntax error.
- Add the last missing templates to override all allauth's displayable
  templates.
- Improve stylesheets.

... to reflect last changes.

django-debug-toolbar is now installed.

Introduce new settings:
- ACCOUNT_HOME_URL, used by 'Site name' link on templates.
- ACCOUNT_DETAILS_URL, used on templates when user is connected.

'username' is registered as extra_data too for Clipper provider.

Template tag 'get_accounts_by_providers' is cleaner.

Remove useless account/settings view. Its content should be displayed
by some profile view.

SOCIALACCOUNT_ENABLED settings (of allauth package) doesn't work well.
Template tag 'is_socialaccount_enabled' provides a better check.
