replace .app with homebrew formula

[masukomi]

There's not much point in the .app. People try and click it to run it (can't blame them) and that doesn't work. Until we've got a proper UI the .app must die and be replaced with something better.

I'll need to create a new Tap for it too.

Tasks:

• [x] the building of a tarball
• [ ] create the formula see docs
• [x] create new tap see docs
• [ ] add to new tap
• [ ] add instructions to README
• [ ] add instructions to web site

new tap is at https://github.com/masukomi/homebrew-masukomi

formula needs to

• [ ] check for presence of existing ~/.config/hey/config.json
• [ ] read it if present
• [ ] if not there then ask where you want your db installed
• [ ] make sure it isn't there
• [ ] download / mv default.db there
• [ ] create config if needed
