don't need -g and chomp, -w returns secret without trailing whitespace
rm unused
change default email
more pathname space handling
add /usr/local/sbin to $path

homebrew installs sleep watcher at /usr/local/sbin
.jshintrc
add sleep watcher scripts
use full path to blueutil, unmount only USB drives

- sleep watcher run via launchd's LaunchAgents has only /{,s}bin and
  /usr/{,s}bin in it's $PATH. So punt and use full path.
- only unmount USB drives on sleep.
npm now uses standard bin path (/usr/local/bin)
undo /usr/local/sbin in $path

only sleep watcher there, not needed from shell...
