Drive homebrew through Script kit

Here's a small script that lets the user drive Homebrew from kit script:

  • list installed formulae / casks
  • install a new formula / cask from a list of all the ones available, minus the ones already installed
  • uninstall an existing formula/cask

Hope it's useful
