* Add shift-to-invert to remaining directional RGB_* keycode pairs
RGB_MODE_FORWARD / RGB_MODE_REVERSE invert their functions when shift is held.
This change adds the same capabilities to the remaining directional RGB_*
keycode pairs. This improves consistency and provides full RGB control in a
keymap containing only one keycode from each pair.
* remove redundant variable
* fix typo
* Fix more typos
