FormMixin get_initial returns an instance-specific dictionary

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In Django 1.3, the ``get_initial`` method of the

:class:`django.views.generic.edit.FormMixin` class was returning the

class ``initial`` dictionary. This has been fixed to return a copy of this

dictionary, so form instances can modify their initial data without messing

with the class variable.

Features deprecated in 1.4
