Fixed #23129 -- Added 'true' and 'false' to `NullBooleanField`. 

JavaScript serializations of forms will sometimes render the boolean
values as the strings 'true' and 'false', in lower case. Rather than
repeat boilerplate in the JavaScript to circumvent this, it seems
reasonable to allow Django to understand the lower-case versions of the
booleans.
