snowe keymap/userspace and Ocean Dream animation (#12477) 
* Add snowe keymap/userspace & Ocean Dream animation

* Add snowe userspace with keymap wrappers and two animations
* Add crkbd keymap
* Add Ocean Dream animation, a cool full screen animation with:
* * twinkling stars
* * meteor showers
* * ocean waves
* * island with palm tree
* * moon with phases

* Disable Luna so travis build succeeds.

* Add more copyrights

* Add pragma once to keycode_aliases.h
