Various additions to the web account manager.
Track if we are accessed via HTTP or HTTPS, and the server name. Track cookies. HEAD method. Various security clean ups. Force HTTPS for account.html. Poor mans Bobby Tables protection. Security token. Validate inputs. Looking up the DNS records for email domain name. Don't allow creation of accounts with god names, leave that for the console. Check if created user name exists already. Double check the passwords and emails. Error messages on dynamic pages. Various clean ups. TODO++
