* Updated personal layouts * tweaked personal * Nightly - Audio Cleanup Refactored the LUTs. Abstracted some of the registers out of audio to use more functional names. Split audio into audio and audio_pwm. WIP * nightly - collapsed code * Added check for note playing to LEDs * Usability tweaks * TWEAE * nightly added extra kcs to keymap common * turned on Plank audio * Added backlight breathing to atomic * reverted accidental merge * Added music and audio toggles to Quantum.c * Redid the audio callbacks * Adjusted default planck layout to use the user tone naming * tabs to spaces * Rewrote the ALL recipe to allow for faster parallel make * tabs to spaces * Renamed custom event functions to be 'startup_user' and 'shutdown_user'. Also moved the prototypes around. * Tweaked pvc atomic layout to work with the pvc planck. * updates midi scale calling
