* refactor yd60mq.h

- four-space indent
- use K<row><col> base32hex notation
- rename LAYOUT to LAYOUT_all (with alias for backwards compatibility)

* refactor yd60mq.c to use led_update_kb()

* align rules.mk to AVR template

* refactor default keymap

Also correct positions for KC_NUHS and KC_NUBS.

* update readme

* add Configurator layout support
