Mackup zap stanza import

Add `zap` stanzas to 88 Casks based on data from the wonderful [mackup](https://github.com/lra/mackup).

I couldn't come up a clever way to leverage the mackup repo, given our current Homebrew-based infrastructure, so am importing some of the relevant data into the Cask DSL, now that we support `zap`.

Note that the `brew cask zap` verb is merged now but not yet in release.

This is an instance of a general problem: `~/.atom` may contain user-created files, the deletion of which could be unexpected or undesirable.
