Find the virtual environments created by Python3.3
Respect explicit encoding declarations in setup.py files.

In Python 2, the exec statement handles encoding for us, but in
Python 3 the encoding must be specified when opening the file
(if it's not specified it uses the system locale encoding, so
previously this would work only if your locale environment variables
specified the same encoding as the setup.py file).

On Python 3.2+ the tokenize.open function is available to interpret
the encoding declaration; fixing this for python 3.0 and 3.1 is more
difficult.
