Added umask

Some people use umask 077 (like me), and it doesn't seem to work. I tried with umask 022 and it worked just fine, so I think we should set the default umask in the script. It would be nice if we can figure out something stricter than 022 as well.

Status command uses silent mode exit codes at all times.
