Paul Hinze 5bbba24bf9 cli: [refactor] rename outdated option internally ... The `Hbc.outdated` boolean was in the way of my implementation of an `outdated` scope for `brew cask outdated`, so I took the opportunity to: * rename the flag internally to `cleanup_outdated` * move the cleanup tests over to rspec and rework them to test in a stubbed cleanroom environment * refactor the implementation of cleanup to make it a bit more testable - most importantly: inject the cache location and outdated config dependencies instead of looking them up from constants Note that there's no change to the user-facing interface, it's still ``` brew cask cleanup --outdated ```		2015-02-07 18:06:51 -06:00
