emdarcher's TADA68 layout

A layout that adds a few extra features on the function layers. Designed for use in a MAC or Unix environment, and has some VIM inspiration.

Added Caps Lock for an extra FN layer with VIM like control on hjlk keys.
Added Breathing Backlight Toggle.
Made the ESC key use GESC for functionality for Grave and Tilde with shift or GUI modifiers.
Added Print Screen, Scroll Lock, and Pause keys on P,[,] keys to add Mac screen brightness control.
- On Mac, Scroll Lock is Brightness Down and Pause is Brightness Up, so with this FN+[ = brighness down, FN+] = brightness up

Moved LGUI to the default MAC Command key position.
