Fixed #2365, #3324 -- Renamed FloatField to DecimalField and changed the code

to return Decimal instances in Python for this field. Backwards incompatible
change.

Added a real FloatField (stores floats in the database) and support for
FloatField and DecimalField in newforms (analogous to IntegerField).

Included decimal.py module (as django.utils._decimal) from Python 2.4. This is
license compatible with Django and included for Python 2.3 compatibility only.

Large portions of this work are based on patches from Andy Durdin and Jorge
Gajon.
