Yosemite support

According to this:

you need to do some additional manual steps after running iesd

iesd -i /Applications/Install\ OS\ X\ 10.10\ Developer\ Preview.app -o Yosemite.dmg -t BaseSystem

Here is the iESD version of the additional hack.

require "iesd/utility/hdiutil"

HDIUtil::DMG.new("/Applications/Install OS X 10.10 Developer Preview.app/Contents/SharedSupport/InstallESD.dmg").show { |installesd|
  HDIUtil::DMG.new("Yosemite.dmg").update { |basesystem|
    system("cp", File.join(installesd, "BaseSystem.chunklist"), basesystem)
    system("cp", File.join(installesd, "BaseSystem.dmg"), basesystem)
  }
}

I would like to wait for a better workaround, so it won't be a built-in feature for now.

Support added in v1.2.2.
