Use function as the return value of `get_url_decorator`. This change
needed because `get_url_decorator` method of `OscarConfigMixin` class
returns function or `None` and not string.

Fixes #3517.

It is done by default, from the "__init__" method of the parent class,
since commit 18eca6f76c.

Fix field lookups in ReportGenerator.filter_with_date_range

Fix checking field's "widget_type" value for CheckboxInput widget

It currently does not include 23:59:59, 00:00:00, and datetimes in the
one second between.

Regression introduced in commit 4bdf5df9b1.

- Remove unnecessary CSS in favour of Bootstrap defaults.
- Remove use of btn-lg whose presentation was being overridden in CSS.
- Fix a few classes on HTML elements.
- Fix required field styling, and remove duplicate non_field_errors on product edit page.

Replace Bootstrap 3 stateful button handling with custom JS for loading state.

Instead of checking for truthiness we should check for equality
(because any status code is `True`).

`override_settings` used instead of updating setting in `setUp`/`tearDown`.
