Improved char_del_option

* Renamed to `char_deletion_code` and moved to login_athena.conf * The value is now using column name instead the number, available options are: * `email` (except a@a.com), * `birthday` (YYMMDD), * `pincode`, * and the last is `Sub-query` which allows you to defines your custom deletion code (as example you ask user for secret code while registering an account, or one-time-password for character deletion) * Extends E-mail length from 39 to 49 * Reordering `0x2717` to make notation with variable length be on last
