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.

In cases like this, for example, shouldn’t we just specify `~/.atom` once, and be done with it? This way, we’re specifying a bunch of individual files (subject to change), and leaving the directory.
