Establish testingfixup-testing

Bring tox defaults into a reasonable state, removing env
aliases that tox no longer supports.

Set up travis.ci, including using dist: xenial to get python
3.7 support. pypy is only in trusty.

In the process add a .gitignore so ignored files don't get
in the way of doing this work.
