#121 PyXB elementary data types do not play well with "copy/pickling/..."

[Dieter Maurer]

As least some elementary data types cannot be copied/pickled.

>>> from pyxb.binding.datatypes import dateTime
>>> from datetime import datetime
>>> from copy import copy
>>> pdt=dateTime(datetime.utcnow())
>>> pdt
dateTime(2012, 2, 16, 9, 58, 2, 659166)
>>> copy(pdt)
Traceback (most recent call last):

trac/121: PyXB elementary data types do not play well with copy/pickling/...

The datetime classes use a pickle format which is a packed structure, but
call the class new method to unpack it. PyXB's schema date/time
datatypes expect string constructor parameters to be lexical values. Define
a reduce method that produces the lexical value as the pickle format.
