Fixed #4228 -- Removed hardcoding of RadioFieldRenderer in the RadioSelect Widget so that the display of RadioSelects can be more easily customized. BoundField.__unicode__ also no longer special cases RadioSelect since RadioSelect.render() now returns a string like every other Widget.

The render() method returns a RadioFieldRenderer object, whose str() is a <ul>.
RadioSelect uses a RadioFieldRenderer to render the individual radio inputs.
You can manipulate that object directly to customize the way the RadioSelect
is rendered.
>>> w = RadioSelect()
>>> r = w.render('beatle', 'J', choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))

You can create your own custom renderers for RadioSelect to use.
>>> class MyRenderer(RadioFieldRenderer):
... def render(self):
... return u'<br />\n'.join([unicode(choice) for choice in self])
>>> w = RadioSelect(renderer=MyRenderer)
>>> print w.render('beatle', 'G', choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))

A RadioFieldRenderer object also allows index access to individual RadioInput
objects.
>>> w = RadioSelect()
>>> r = w.render('beatle', 'J', choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
