Combine all OS X-release specific Casks

[rolandwalker]

These can be fully captured in the one Cask using if and depends_on :macos. This has probably already been done for some in the main repo

• command-line-tools-lion.rb (removed)
• command-line-tools-mountain-lion.rb (removed)
• daisydisk-snowleopard.rb
• keyremap4macbook-mountainlion.rb
• macvim-mountainlion.rb
• middleclick-mountainlion.rb
• middleclick-snowleopard.rb
• paraview-lion-python27.rb

Edit: some Casks can stay here instead of integrating to the main repo

Now that I’m looking into it, we could probably outright remove command-line-tools. After all, the command-line-tools are exactly what homebrew requires you to install to use it. This means that to use homebrew-cask you already have them installed anyways.

[rolandwalker]

That makes sense, but on the other hand, someone added command-line-tools*.rb, so they must have had a purpose in mind.

@albinoz , what's the use-case here?

[vitorgalvao]

Marking keyremap4macbook as done, even though the fix isn’t yet ready for merge. This also allows us to mark it in #552. If we remove command-line-tools, those can be marked there as well.

I don’t know the origin of the links for command-line-tools (i.e. where @albinoz found them originally), but they’re on Apple’s domain, so integrity shouldn’t be an issue. On Apple’s developer portal, the links are different (and appear to be downloadable only when logged in). The cli tools for the latest versions of OS X also have a different name (“command line tools for xcode”), while some of the older ones have both. I haven’t looked in much depth, so I’m not sure if there’s some important difference.
