#7 Test broken

[Marco Beri]

In test/AESbench.py change code:
if out=="CBC128": encoder = aes.aes(key128,"CBC",IV)
if out=="CBC192": encoder = aes.aes(key192,"CBC",IV)
if out=="CBC256": encoder = aes.aes(key256,"CBC",IV)
with:
if out=="CBC128": encoder = aes(key128,"CBC",IV)
if out=="CBC192": encoder = aes(key192,"CBC",IV)
if out=="CBC256": encoder = aes(key256,"CBC",IV)
