Django-tables2

- Change order of logic in `get_table_pagination` to make sure we are able to override the paginator using `View.paginator_class` attribute.

- The `klass` argument to `Table.paginate()` is renamed to `paginator_class`
- Table views/mixins now take `ListView` attributes `paginator_class` and `paginate_orphans` into account.

- Fixed a bug in the implementation of [606](https://github.com/jieter/django-tables2/pull/606)

- Added the ability to change the html attributes for `thead`, `tbody`, `tfoot` tags [606](https://github.com/jieter/django-tables2/pull/606) by [roelbouwman](https://github.com/roelbouwman)

- Added `LazyPaginator` to prevent making `.count()` queries ([604](https://github.com/jieter/django-tables2/pull/604)).

- Added `linkify_item` keyword argument to `ManyToManyColumn`, fixes [594](https://github.com/jieter/django-tables2/issues/594)
- Fixed an encoding issue in `README.md` preventing installation in some environments.
