Fixes randomisation of doctests (#37)

* Fixes issues with doctests reported in #36 - ``class``, ``package`` and ``module`` didn't work because ``DoctestItem`` doesn't have ``cls`` or ``module`` attributes. Thanks @tobywf.
* Deprecates ``none`` bucket type.
* With tox, run tests of pytest-random-order with both pytest 3 and 4.
