Fall back to an unversioned Python executable if python2.7 doesn't
exist.
Select either the 'Scripts' (Windows) or 'bin' (everything else)
directory to locate Python binaries and scripts installed in the project
virtualenv.
Set the default locale on Windows instead of 'en_US.UTF-8'.
Append a '.exe' extension to the program passed to swaddle if on Windows
and the program doesn't have an extension.
Convert UNSECURE_RANDOM_STRING to a byte string.

This fixes the case where the native encoding contains characters
outside of the ASCII range (0 <= c <= 127).
