Tvinga SSL med glftpd

new glftpd.conf settings :
with these you can deny TLS access to some people
check the examples

NOTE : you cannot use =GROUP or FLAGS in these 2 lines !!!! userfile isnt
loaded yet you can only use -username and *

EXAMPLE :
#not allow lamer to use TLS mode
userrejectsecure -lamer !*
#allow only hoe to use insecure access
userrejectinsecure !-hoe *

basically to create 100% secure site you will want to use this setting :
userrejectsecure !*
userrejectinsecure *
denydiruncrypted *
denydatauncrypted *
