Po-util: The Ultimate Local Particle Experience for Linux and macOS

I have added support for Atom Build shortcuts for po-util. The shortcuts are interpreted by the atom build package, and the corresponding po-util command is run.

Atom Build Shortcuts:
  Build        CTRL-ALT-1   These shortcuts allow you     This requires the
  Flash        CTRL-ALT-2   to run common po-util         "build" package for
  Clean        CTRL-ALT-3   commands quickly while        Atom.  Get it with:
  DFU          CTRL-ALT-4   using Atom.                   "apm install build"
  OTA          CTRL-ALT-5

As always, po-util can be installed with:

curl -fsSLO https://raw.githubusercontent.com/nrobinson2000/po-util/master/po-util.sh
./po-util.sh install

Or if you already have po-util just run:

po update
