Add phantomjs puppet script

* Most of the puppet script originally by Stefan Kojic with some changes:
  * Using Exec to specify paths to avoid having to say /bin/tar, etc.
  * Extracting/managing things in /tmp
  * Extracting to /usr/local/bin instead of /usr/bin
  * Split up variable into 3 variables
