Added WS2812 support for KC60 (#419)

* Added WS2812 support for KC60

* Reorganized WS2812 support into its own keymap

* Fixed relative link in README

* Moved WS2812 mention in README to the bottom

* Fixed titling in WS2812 README

* Reverted KC60 Makefile and default keymap back

* Moved RGB specific config.h to ws2812 keymap folder

 ======================
 
 ## Quantum MK Firmware
-
 For the full Quantum feature list, see [the parent README.md](/README.md).
 
 ## Building
-
 Download or clone the whole firmware and navigate to the keyboard/kc60 folder. Once your dev env is setup, you'll be able to type `make` to generate your .hex - you can then use the Teensy Loader to program your .hex file.
 
 Depending on which keymap you would like to use, you will have to compile slightly differently.
@@ -22,3 +20,8 @@ To build the firmware binary hex file with a keymap just do `make` with `KEYMAP`
 $ make KEYMAP=[default|jack|<name>]
 ```
 Keymaps follow the format **__\<name\>.c__** and are stored in the `keymaps` folder.

+## Quantum MK Firmware
+For the full Quantum feature list, see [the parent README.md](/README.md).

+## WS2812 Support
+By default, it is now setup for 16 LEDs on the PF5 breakout pin. See [included image](ws2812_wiring.jpg) for wiring reference.
+
+### Build
+To build this keymap with WS2812 enabled, simply run `make KEYMAP=ws2812`.
