Options can be passed on the command-line and/or using the HOMEBREW_CASK_OPTS environment variable (which has lowest priority). There is a single --appdir=PATH option right now, but this commit enables future awesomeness! Other minor changes: * `brew cask help` now returns the same thing as `brew cask` instead of saying there was “no such command as help”. * The HEREDOC block now uses Homebrew's #undent instead of the customed-rolled #gsub version. Cleaner and more flexible. * `Cask.set_appdir` has been renamed to `Cask.appdir=`. This is more Rubyish, and of little consequence (the only place it was previously used was in the tests).
