handling of dates fails for year 0000

[matthiasgleichauf]

>>> import validictory
>>> object = {'mydate': '0000-10-03T15:35:05Z'}
>>> schema = {'type': 'object', 'properties': {'mydate': {'type': 'string', 'format': 'date-time'}}}
>>> validictory.validate(object,schema)
Traceback (most recent call last):

>>> 

fails with: validictory.validator.ValidationError: Value '0000-10-03T15:35:05Z' of field 'mydate' is not in 'date-time' format

which I believe is a bug.

Environment: python 2.7 from ubuntu-sources (12.04) validictory 0.8.3 installed via pip

sorry, 0000-10-03 isn't a valid python datetime, mainly because there wasn't a year zero: http://en.wikipedia.org/wiki/0_(year)
