require most commands to succeed; cleanup on install failure

- 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

fix snip cask, which does not have an app to link

looks like snip uses a pkg to install directly to /Applications, so
`link` neither works nor makes sense here

also add a proper `uninstall` line for it
