* Add nordic keymap
Changes from default:
- Change button right of `LSHIFT` to `KC_NUBS`
- Add some more keys to the second layer.
* Add sleepmode functionality
Added a sleepmode, this turns of the rgb_matrix if no key was pressed for x minutes. Not default on, so you have to enable it by defining `SLEEPMODE_ENABLED`.
* Move all sleepmode config to config.h, rename keymap
- Move all configurations for sleepmode to keymap config.h
- rename keymap to include reference to it having sleepmode (suggestion from guy the discord-server)
- add copyright in config.h

* BM60RGB ISO: fix and extend default keymap
- correctly assigns the Non-US Backslash and Hash keys
- adds Function and Navigation keys
- use KC_GESC instead of KC_ESC to make Grave accent available
* Update layout macro
The layout is the ISO equivalent of QMK's `LAYOUT_60_ansi_arrow`.
