* Include date hierarchy in quick removal links
* use date field name in removal link
* reduce diff
* tweak some details
* start adding tests
* use mock without spec :(
it's not easy to instantiate ChangeList, and speccing from
the class means that many attributes are not recognized
* more tests
* more tests
* more checks for generated URLs
* better tags and tests
* compat for tox 4
