* Enabled unicode support and send_unicode function

* Unicode cleanup

* More unicode tweaking

* Update EEPROM stuff

* Account for keyboard macros

* Switch Equal to Plus on Ergodox

* more tweaks

* Minor Unicode tweaks

* Correct matrix printing for keylogger

* Fix unicode functions

* Fix unicode mode set since it actually uses EEPROM

* Re-add DISABLE_LEADER

* Ergodox is easier to hit the tapping term, fix that

* Fix stupid type on unicode mode check

* Preliminary CRKBD/HeliDox support

* Fixes to Helidox

* Cleanup userspace from old merge stuff

* Remove CCCV sounds
