Summary: warn on assignment to None, True, False

Initial Comment:
This patch issues a warning when None, True, or False
is assigned to.  I don't know what the text of the
warning should say, but that's a minor matter.

Nice, but doesn't catch enough cases. E.g. using None as an
argument name, assigning to an attribute named None, "import
foo.None", "from foo.None import bar", "from None import
bar", "from None.foo import bar", using None as a keyword
argument in a call: "f(1, 2, None=3)".
