Subject: xtonhasvim cleanup (#2947)

* FORK!

* WIP - just how i like it

* empty

* more movement

* mouse keys

* more vimminess

* append/insert shift

* WIP - vim macros

* blocked out layer below in cmd mode.

also, about to restart my cmd approach.

* WIP - new vim layer

ripoff of the ergodox one, but rewritten as a state machine.

* debugged some, got key repeat working

* moooar coverage

* moooar coverage

* regular vis mode

* basically done with basics.

* some refactoring

- common movement sequences into helper function
- added some rgb controls

* modkey passthru feature

* stdized on cmd-left/right instead of ctrl-a/e

sadly. as there's no reliable shift-ctrl-e

* indicator lights

* moved vim layer into userspace

* cleaned up some yanking edge cases

* docs and some tweaks to layerescapes

* updated/added license strings

* updated comments

* moved config changes to keymap

* spurious changes removed

* cleanup pass, HT drashna for suggestions

- used _keymap() pattern to better modularize event processing in userspace
- made some static things static
- removed unused function
- improved reset.
