Change logic in how root / non-root users are handled; root is no longer part of the multi-select user list.  The choice whether root is able to login is wholly determined by the value of PermitRootLogin.  If this is set to yes, then the back-end script only handles the creation of .ssh sub-dir and copying of root pub key if exists.

Some general gui tweaks to the on screen formatting.  Also some additional version check conditional logic for when local version is unknown.

Fixed auto-start of SSHD upon reboot
