Summary: remove tiny anomaly re bool()
Initial Comment:
builtin types called without arguments -- int(), long(), float(),
list(), dict(), tuple() -- return the false value of that type.
bool() called without arguments raises an exception
instead. This patch makes bool behave like the other builtin
types, and adds tests for this "call type without arguments"
behavior (for bool AND the other six builtin types).

I'll check this in, because I like the idea.
I note there's a flaw in the execution: after
ok = (x != NULL) && PyObject_IsTrue(x);
the following line
if (ok < 0)
makes no sense; C's && doesn't work like Python's 'and', it
always returns either 0 or 1.
I'll fix this.
