[luau] Saving in /home

[Warren Togami]

Also remember that the umask for netatalk needs to be set.  I don't know
how to do this for the /home directories though...

Making all home directories 777 really makes me nervous.  It might work
for a school like Liholiho, but otherwise it is a disaster waiting to
happen.  We really need to fix netatalk and get a proper ACL filesystem
working on your server in order to do the job "right".

For now though, I disabled the nightly cron script that "fixes"
permissions within /home.
