[Python-3000] Removing functions from the operator module

[Collin Winter]

PEP 3100 mentions that isCallable() and sequenceIncludes() are to be
removed from the operator module in Python 3000 because there are
better, more obvious ways of spelling these things.

So, on that note, should operator.truth() and operator.abs() be added
to the to-be-removed list, in favour of the builtins bool() and abs()?
