In test_obj.py there are PUT tests that are specific to the Putter
type and others that apply to any Putter type. This patch refactors
them into separate classes to provide greater clarity and to allow
common tests to be applied to each Putter type.
Taking this infrastracture out and ahead of PUT+POST itself allows
it to be reviewed much easier, especially when you look at the diff.
