Remove unused import
Add a little hack to allow running with both Python 2 and 3.
Encoding info needed for Python2.
Appropriately import StringIO depending on the Python version.
Update Python versions for Travis-CI test bot.
Print timezone with the date.
Update tests to consider timezones.

Unfortunately we have to resort to regex as we can't reliably predict the
timezone of the user running the tests.
Merge branch 'issue7'

Fixes issue #7.
Remove unused import.
For now, only use Travis for 3.2.

It should be noted that local tests for 3.1 pass. Local tests and tests on other
peoples' machines with 3.3 pass as well but seem to fail on Travis for a single
non-critical test. Removing 3.3 from Travis testing for this reason until I can
investigate it further.
Merge branch 'python3'

Fixes issue #6.
