* redoes matrix pins, abstracts backlight code for B5,6,7 * slimming down keyboard stuff, backlight breathing implemented * don't call backlight init when no pin * cleans up user/kb/quantum calls, keyboard files * fix pvc atomic * replaces CHANNEL with correct var in breathing * removes .hexs, updates readmes, updates template * cleans-up clueboards, readmes to lowercase * updates readme
