[Catalog-sig] "python 2 only" classifier

[Chris McDonough]

Hi,

It'd be useful to have a Trove classifier that signified "the authors
have no current intention to port this code to Python 3".  Such a
classifier could be used by e.g. http://python3wos.appspot.com/ to
present a more accurate picture of the current state of porting efforts.
Currently automated reports like that are bad PR because there's no way
to communicate the intent.

Perhaps:

  Programming Language :: Python :: 2 :: Only
