Backlighting for JJ40 and underglow initialisation code (#2260) * Cleanup Mechmini keymap. Once the custom RGB function is defined, there is no need to manually handle RGB code. * Change default to KEYMAP_MIT, not KEYMAP_OFFSET * Add custom RGB code for JJ40 * Reset Mechmini advertised power draw to 500. Will have to test actual maximum power draw later. * RGB working on JJ40. * Fix: saturation increase/decrease flipped * Add new directory for my custom keymap with RGB keycodes * Swap LAlt and LGUI * Update JJ40 max power draw with measured value * Update: fun40 rules.mk to enable underglow; earlier failed Travis CI * Fix: init RGB LEDs on boot. Also added HHKB-like keymap for XD60. * Super rudimentary backlight test, init RGB LEDs on boot * Backlighting works - stays on for now * Toggling working * Now can override backlight.c functions. Problem was functions in backlight.c weren't called before due to a lack of matrix_scan_quantum() in matrix.c * Timers not working * Delete global.h * Cleanup * Compiles * Good sign: LEDs stop working again * Handle timer1 overflow * Progress: fix: forgot to init * Backlighting fully working now except breathing. * Revert keymap to original keycodes * Update XD60 keymap README * Update JJ40 keymap with backlight toggles * Breathing working just fine. * Update references * Add backlight_set() call * Cleanup code to disable backlight * Fix: does not compile * Fix: missing call to rgblight_task. * Testing with BACKLIGHT_BREATHING * Cleanup * Cleanup comments * More commenting cleanup. * Do not enable BACKLIGHT_BREATHING by default
