Summary: datetime.replace could take a dict

Initial Comment:
Python 2.4.1.

datetime.replace uses its kwargs to specify the fields,
which I found a bit surprising.  It could also take an
equivalent dict.  (Failing that, it could have a fuller
docstring.)

What I was actually trying to do was round to the
nearest half hour.  floor and ceil methods taking a
timedelta would be nice too.

Any function accepting keyword arguments can already be
called with an equivalent dict using the ** notation
(similar to tuple unpacking):

>>> from datetime import date
>>> d = dict(day=26, year=2004)
>>> date(2001, 1, 2).replace(**d)
datetime.date(2004, 1, 26)
