Added variable in .env to enforce certain domains in account registrations (#1589)

Allow REQUIRE_MAIL_DOMAIN to not exist in addition to it being empty

Undo changes in config/locales/de_DE.yml

changed .env variable name to GREENLIGHT_ACCOUNT_HD; allowed only comma and no whitespace as separator

Allow the admin to change email-addresses, just enforce domain on registration
