Regenerate proftpd config fails in update

patch for asking the user for ftp_user and pass if necessary

In ispcp-setup this is done on line 154ff:

# # ispCP ftp SQL user questions; #

$rs = ask_db_ftp_user(); return $rs if ($rs != 0);

do {

$rs = ask_db_ftp_password();

} while ($rs == 1);

ispcp-update doesn't do this, but the values which are used for DATABASE_USER and DATABASE_PASS are set by these two functions (ask_db_ftp_user() and ask_db_ftp_password()).

So I suppose to ask for these values in setup_ftpd() if the needed variables aren't set. I've just added where I've made this change in the ispcp-setup-methods.pl - setup_ftpd() function. Hope this will do the job.

you're right, we can overwrite it without any trouble; noone needs the password ...
