Adds Minidox Keyboard (#1487)

Browse Source 
* merge

* line ending stuff

* Added MiniDox keyboard folder / configs / and some keymaps

* Updated minidox rev1 config, and readme. Also updated that_canadian keymap to include RGB

* cleaned up that_canadian keymap comments

* Fixed RGB being enabled by default, now it must be turned on at the keymap level

A compact version of the ErgoDox
Keyboard Maintainer: That-Canadian
Hardware Supported: MiniDox PCB rev1 Pro Micro
Make example for this keyboard (after setting up your build environment):
make minidox-rev1-default
See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.
