* zweihander-osx: Remove app keys, etc.

- add right command keys
- add F16 on ;' for Siri
- remove command-Q (too easy to hit)

* Rename zweihander-osx to zweihander-macos

zweihander-macos: / / ^ → / / ⌥; README revamp

zweihander: rename, ⌃ → ⌥, README revamp

* Zweihander: swap space, enter keys

Left thumb needs a break.
