Keymap: Redox: add a new Colemak keymap, macOS oriented. (#3861)

* Add my own keymap to the list of available Redox keymaps.

This keymap is a Colemak keymap, and is meant to be used on Mac OS.
More information can be found in the readme.

* Fix "macOS" typo and remove mention of the license.

This directory inherits the project's license.

* Add missing custom keycode.

* Address feedback from PR review

- Remove deprecated code
- Remove RGB logic since it is overwritten by code running later.

+# A Colemak keymap for the Redox keyboard
+
+----
+![jeherve-redox-layout-3](https://user-images.githubusercontent.com/426388/45171716-69888200-b203-11e8-822d-7bc91f9f6c07.jpg)
+
+----
+
+This keymap is **a work in progress**, and is meant to be used on macOS, with the "Unicode Hex Input" keyboard input.
+
+![macOS keyboard input setting](https://user-images.githubusercontent.com/426388/43962498-1ee9e3fc-9cb8-11e8-88e3-dbb068ec5c67.png)
+
+I may change a lot of the keys over the next few months, and will update this repo when I do so.

+
+## Layers
+
+My keymap uses 5 layers:
+
+1. The default base layer, using [Colemak](https://colemak.com/).
+2. A Symbol layer, so all symbols can be accessed from the home row. (top right legends)
+3. A Navigation / Media layer, with both sound control and arrows on the home row. (bottom right legends)
+4. An international / Emoji layer so I can type accented characters commonly used in France and in Hungary, as well as a few Emoji I often use. (top center legends)
+5. A keyboard control layer, not pictured above, allowing me to control the LED lighting as well as the keyboard debug functions.
