[Feature Request] Make it installable with HomeBrew cask

[erikw]

First, thanks for providing this dictionary. Very much appreciated!

I have an idea for making it easier to access and use. It would make it a lot easier of this package was installable as a HomeBrew cask. Then on a new computer one could do simply $ brew install macfolket, or even put this in one's standard setup script or Brewfile.

It would probably mean to package this differently as a cask should not pop up an UI installation dialog but handle it in CLI only.
