Update feature: Make Auth secure by creating auth hash during install.

This will break old installations, users can not be able to login.
Either user need to reset the password or add the old hash to site config.
ex: site.auth_hash_key = e41eb68d5605ebcc01424519da854c00cf52c342e81de4f88fd336b1d31ff430
This is a security fix, can't be skipped, making gleez more secure.
