* Revamp replicaJunction keymaps
Updates both the replicaJunction Ergodox and Atreus keymaps and moves
most of the logic into a new user directory.
* Cleanup as requested in #3589
* Slightly increased TAPPING_TERM
* Fixed typo in #pragma once
* Fix TAPPING_TERM redefined in config.h
* Add include of replicaJunction.h
Due to the tap dance references, without this include, I was getting
compiler errors about both internal QMK items like
`qk_tap_dance_state_t` and constants defined in my replicaJunction.h
file like TD_LAYER_TOGGLE.
Also remove some commented-out code that defined an enum which has since
moved to replicaJunction.h.
* include variables and .h files as pp directives
* start layout compilation
* split ergodoxes up
* don't compile all layouts for everything
* might seg fault
* reset layouts variable
* actually reset layouts
* include rules.mk instead
* remove includes from rules.mk
* update variable setting
* load visualizer from path
