Updated Mail vacuuming script

Another year, another new operating system, another update to the Mail Vacuuming script that I first posted in 2012. It’s an AppleScript that performs the simple task of optimizing the database that Mail.app uses for all of your messages, speeding up load and search times.

The latest version of Mail now uses a sandboxed container (in addition to a V5 bump). I personally haven’t used Mail in years, so the fixes came from @lbutlr. The gist is updated, and the code is below.
