Enigma 1.30 now in Homebrew core

[Sidney Markowitz]

The changes for the new release of Enigma 1.30 have now been accepted by 
the Homebrew project.

It is no longer required to use the enigma-game/enigma tap to install 
Enigma in Homebrew.

The new instructions for installing Enigma 1.30 on macOS in Homebrew (no 
change for installing Enigma-1.30.dmg from the download site without 
Homebrew) are:
   brew install enigma

You can install as an app bundle in /Applications using

   brew install --cask --no-quarantine enigma
