#4312: addition of defaults argument to newforms save()

I'd like the ability to call save() on a form and insert some values for
fields (e.g., non-editable or to the instance before it is saved. This
way, calling save(False) to return an object which is subsequently
manipulated then saved again can be avoided. I'm not sure if 'defaults'
is the best name for this argument, but that's what I've implemented for
now. For example:
Given these models:
{{{
from django.db import models
class Foo(models.Model):
name = models.CharField(maxlength=16)
class Bar(models.Model):
name = models.CharField(maxlength=16)
foo = models.ForeignKey(Foo, editable=False)
}}}
Here is the example:
{{{
>>> from django import newforms as forms
>>> from mysite.myapp.models import *
>>>
>>> my_foo = Foo(name='My Foo')
>>> my_foo.save()
>>> Form1 = forms.form_for_model(Bar)
>>> form = Form1({ 'name': 'My Bar'})
>>> form.is_valid()
True
>>> form.save(defaults={ 'foo': my_foo })
<Bar: Bar object>
>>> Form2 = forms.form_for_model(Bar, fields=('baz'))
>>> form = Form2({})
>>> form.is_valid()
True
>>> form.save(defaults={ 'name': 'My Bar 2', 'foo': my_foo })
<Bar: Bar object>
>>>
}}}
