The default ksh in OpenBSD throws the following error:
===
$ . hacking/env-setup

This uses the `devel` branch when displaying the travis-ci status badge.

Add tox and travis-ci support

Add tox integration to run unittests in supported python releases.
Travis-CI is used for test execution.

Additionally, the unittest TestQuotePgIdentifier was updated to support
using assert_raises_regexp on python-2.6.

it (when we send it to jinja2) because jinja2 cannot handle non-ascii

use to_unicode() in _jinja2_vars if type is str.
