BugFix: Fix dateS3toPython to gracefully handle returned date that are not in GMT to respect iso8601.
Ex.: 2014-03-05T18:45:50+00:00 instead of 2014-03-05T18:45:50Z
Fixes date functions to return timestamps based on UTC time value. + so simplified formatDateTime().
Merge branch 'master' of git://github.com/fviard/s3cmd into fviard-master
