SSL subject name retrieval

[olliencc]

For websites try and connect via SSL and retrieve the certificate subject name,

This should extract both the Subject Distinguished Name and the Subject Alternative Name (if this attribute is in the certificate).

My initial testing has shown Python's SSL support to be somewhat lacking. Despite the documentation suggesting it can decode certificates into a python dictionary, under Windows I either get a binary representation or an empty dictionary. We'll need to add another dependency for doing certificate decoding.
