Travis CI

Maybe you don't care about Travis CI because you'd rather set up the OpenStack infrastructure such as Jenkins and Gerrit -- if you don't care, you can close this. But just in case it's useful, even as a temporary measure until the other stuff gets set up, here goes.

```
$ tox
...
  py26: commands succeeded
  py27: commands succeeded
  pypy: commands succeeded
  py33: commands succeeded
  py34: commands succeeded
  congratulations :)
```
