Title: Respect the $TZ environment variable to show local times if requested

It would be nice for s3cmd to print timestamps in the local time zone. This pull request makes s3cmd honor the fairly-standard "TZ" environment variable and, if the pytz library is installed, display timestamps in the correct timezone.

pytz internally memoizes timezones, so this isn't quite as expensive as it looks at first blush.
