  Fix broken doctests and run doctests on all versions

``zope.catalog.tests.placelessSetUp`` was removed so doctests didn't
run anymore.

Also some project updates:

- Remove claim to support Python 3.3. This hasn't been tested on
  Travis for some time. Also remove 3.3 from tox.ini.
- Modern coverage tox environment.
- Run doctests on travis.
- Fix broken badge and add version badges.
- Use modern PyPy on Travis.
- DRY in 'rtd.txt'. Incidentally, this probably fixes #9
