add an option --github to brew cask info [Cask] to show a cask's GitHub source Page like brew info [formula] --github

[MikeMcQuaid]

Could this be put into brew info instead of brew cask info?

@MikeMcQuaid
Now brew info [Cask] --github cause an error like below.

brew info atom --github
Error: No available formula with the name "atom" 

When args is Casks, args.named.to_formulae in cmd/info.rb would not return Cask and cause an error.

  def info
    args = info_args.parse
    --< omit >--
    if args.json
      --< omit >--
    elsif args.github?
      raise FormulaUnspecifiedError if args.no_named?

      exec_browser(*args.named.to_formulae.map { |f| github_info(f) })

@hyuraku you can use args.named.to_formulae_and_casks but you'll need to refactor the github_info function to handle casks.

I improved that brew info [Cask] --github and brew cask info [Cask] --github can work.

I pulled and tested this locally, (brew info [Formula] --github, brew info [Cask] --github, brew cask info [Cask] --github), and it works as expected.

Also tested for the cases where a Formula and Cask have the same name, and it defaults to the Formula and suggests the full tap name for the corresponding Cask (as expected).

I did not even know about the --github flag for Formula, very handy! Even more handy now that it works for Casks too.

Great work @hyuraku.

Thanks again @hyuraku!
