* Move all timezone usage to use pytz 

* Add support to timezone aware datetime conversion
* Correct capitalization of Brazil/DeNoronha

All previous timezone names are tested against the new pytz based timezones.
This test shows that the following zones changed when pytz support was added
(i.e. not in this commit):

t1 = time.mktime(datetime(2002, 1, 1).timetuple())
t2 = time.mktime(datetime(2002, 7, 1).timetuple())
expected_failures = [ # zone.info(t1)     newzone.info(t1)     zone.info(t2)     newzone.info(t2)
    'Jamaica',        # (-18000, 0, 'EST') (-18000, 0, 'EST') (-14400, 1, 'EDT') (-18000, 0, 'EST')
    'Turkey',         # (10800, 0, 'EET') (7200, 0, 'EET') (14400, 1, 'EET DST') (10800, 1, 'EEST')
    'Mexico/BajaSur', # (-25200, 0, 'MST') (-25200, 0, 'MST') (-25200, 0, 'MST') (-21600, 1, 'MDT')
    'Mexico/General', # (-21600, 0, 'CST') (-21600, 0, 'CST') (-21600, 0, 'CST') (-18000, 1, 'CDT')
    'Canada/Yukon',   # (-32400, 0, 'YST') (-28800, 0, 'PST') (-28800, 1, 'YDT') (-25200, 1, 'PDT')
    'Brazil/West',    # (-10800, 1, 'WDT') (-14400, 0, 'AMT') (-14400, 0, 'WST') (-14400, 0, 'AMT')
    'Brazil/Acre',    # (-14400, 1, 'ADT') (-18000, 0, 'ACT') (-18000, 0, 'AST') (-18000, 0, 'ACT')
    ]

The most likely explanation for this is that the old database was out of date.
