hgfixes: added a fixer to convert changes in the email package

This patch adds a fixer that accounts for changes in python packages, as the
framework provided by lib2to3 is only able to track changes in module names.
This fixer (hopefully) can fix any change in one-level hierarchies.

To exemplify, this fixer can successfully change an import from
"email.MIMEMultipart" to "email.mime.multipart".

#!/usr/bin/env python

import errno, os, sys

for f in sys.argv[1:]:
    try:
        print f, '->', os.readlink(f)
    except OSError, err:
        if err.errno != errno.EINVAL:
            raise
        print f, 'not a symlink'

sys.exit(0)
