- add `run!` method which raises if command does not succeed - use `run!` when the command we are running must succeed for things to move forward. this should help produce clearer error messages in failure scenarios. - move caveats earlier in the install process so reports can be made about potential failures - remove the destination tree on cask install failure, so the cask will not be considered installed
