[pycrypto] Pycrypto working with python 3.0 or 3.1

[Christoph Tapler]

Hi Grail,

Following replacement - I have used AES as an example - seems to work
fine:

From:
     from common import make_block_tests
     return make_block_tests(AES, "AES", test_data)

To:
     from . import common
     return common.make_block_tests(AES, "AES", test_data)

In some files, you also need to remove the "import common import dict" 
at the beginning of the files. According to the comment, this was only
needed for Python 2.1 / 2.2. Hence that removal should not negatively 
affect functionality.

Unfortunately I don't have enough time to do all the replacements in
the next days. I could send you a patch on weekend earliest.

Cheers,
Christoph
