• [+] added __lang() method in trait Helpers. Supported new to legacy key conversion.
• [-] removed duplicated emails from database_emails_banned.sql
• [-] removed strict PDO type from constructors of Auth and Config. This is done because not only the PDO, but also a wrapper over the PDO can be passed as a connection.
• [*] changed some message codes (for more clarity)
• [+] for a number of configuration variables, the zero value is now available. A value of zero means that the check for this rule should be skipped. So, verify_email_min_length = 0 means that the email is not checked for the minimum length.
• [+] added two rules for setForgottenDefaults(): verify_email_valid TRUE, verify_email_use_banlist TRUE
• [+] added setCaptchaValidator implementation
• [+] Config::__set() now saving settings to DB only if Config type is SQL
• [-] removed database_informix.sql
• [*] fix tests: runs testRegister() and testLogin() in separate process (prevents 'headers already sent' error)
• [*] fixed setLocalization() method
