Validate Emails Addresses & Other Security Tweaks(#385)

* Use generatePassword rather than a shortened hash

* Tweak how cron credentials are created

* Use the standard PHP function to validate emails

* Validate and sanitize emails

* Fix typos

* Use idn_to_ascii when validating emails

* Only use idn_to_ascii when validating the email

* Fix tests

* More text fixing

* We should only have one more failure now

* sighs

* Disable that since it's failing for no reason
