- remove some crufty old testing options

- reestablish the "bootstrap" system of loading the test runners
in testing/plugin; using the updated approach we just came up with for
alembic.  Coverage should be fixed now when running either py.test or
nose. fixes #3196
- upgrade tox.ini and start using a .coveragerc file
