Hodgepodge of fixes

Julien, as the name indicates, the patches are more of a collection of fixes than anything consistent or polished. If you want me to remove or rework some patches or put them in sane patch sets (like I've done before), just say so.

This is more of a query of what do you want to see included in your version than a real push request (not that I will mind if you do pull it :) ).

As for the fixes included:
 - updated Alexa top 1m list
 - improvements to scanning, including: SNI support, handling of google ECDSA configuration, IP addresses, etc.
 - collecting OCSP stapling support info
 - collecting TLS Session Ticket hints
 - fixes to result parsing
