fix problems with Brew (on OS X)

brew update && brew upgrade brew-cask && brew cleanup && brew cask cleanup

When I run

brew update && brew upgrade brew-cask && brew cleanup && brew cask cleanup 

I get: Error: brew-cask 0.53.3 already installed

This can be fixed with:

brew update; brew upgrade brew-cask;  brew cleanup ; brew cask cleanup
