* Changed behavior of _DVORAK layout's KC_RSFT to SFT_T(KC_ENT) for flexibility's sake.
Updated the rest of the keymap to reflect the current (as of 19:37 on 08 Aug 2018) default
layout and default makefile.
Atreus: Removed home row Shift. It's under the thumb anyway. Also replaced dual modifier keys with macro keys (cut, copy, paste, undo).
Ergodox: Made Colemak the default layer instead of Dvorak. Also began the process of bringing it in line with the Atreus layout I've been working on.
