cwm updates for python 2.6

Here are some module name tweaks and one method rewrite that take care 
of the deprecation warnings in python 2.6 (which a lot of people might 
see this week due to the new Ubuntu release).

I did not test these except to confirm that cwm starts up more quietly. 
The only controversial change would be my change in term.py where 
instead of putting the refcount-protection line in a __new__ method 
(which is unfortunately intertwined with the signature of this __init__ 
and the superclass's __new__), I just put the refcount-protection in the 
actual __init__.

The patch is for the latest 2000/10/swap/ source, which is from 
2008-09-03, I think.
