Summary: Check result of can_sign() for public keys

Initial Comment:
In the case of calling can_sign() applied to a PUBLIC key:

publicKey.can_sign()

its result is True, even though signatures can be performed by private key only.

I've noticed this behaviour for DSA and qNEW algorithms.
However, if I try to sign a message using sign() and the PUBLIC key, the expected error message is issued. So sign() function seems to be fine.
