global name 'urllib' is not defined in pyDAL==17.11

[ngodinhnhien]

if not decode_credentials:
    credential_decoder = lambda cred: cred
else:
    credential_decoder = lambda cred: urllib.unquote(cred)

This should be

if not decode_credentials:
    credential_decoder = lambda cred: cred
else:
    credential_decoder = lambda cred: unquote(cred)

I know this will be fixed in next version, but currently my web2py application is using pyDAL 17.11, upgrade pyDAL to later version will cause my app behaves incorrectly (or crashes).
