1.2.2 - fixed bug with marks on cases with pytest 3.3

Marks on cases are now also working with pytest 3.3. Fixed #23

Ids for marked tests are now better managed. A new function get_pytest_parametrize_args is now used to transform the list of cases obtained by get_all_cases(module), into the list of marked cases and ids required by @pytest.mark.parametrize. The doc has been updated to explain this for advanced users wishing to perform this step manually.

See documentation page for details.
