Creates a layouts/ folder for keymaps shared between keyboards (#1609)

* include variables and .h files as pp directives

* start layout compilation

* split ergodoxes up

* don't compile all layouts for everything

* might seg fault

* reset layouts variable

* actually reset layouts

* include rules.mk instead

* remove includes from rules.mk

* update variable setting

* load visualizer from path

* adds some more examples

* adds more layouts

* more boards added

* more boards added

* adds documentation for layouts

* use lowercase names for LAYOUT_

* add layout.json files for each layout

* add community folder, default keymaps for layouts

* touch-up default layouts

* touch-up layouts, some keyboard rules.mk

* update documentation for layouts

* fix up serial/i2c switches

+# Norwegian Colemak setup with osx/pc toggle
+
+## Motivation
+I wanted a Norwegian Colemak setup that worked in a similar way on both my Mac and PC. I  also wanted it to translate from a standard Norwegian keyboard OS setup.
+
+## Overview
+The setup is created to be programmer friendly.
+- Most of the symbols used in code can be activated without using layers or shift key.
+- You can reach the IDE/OS shortcut activators(Ctrl, Win/Cmd, Alt, Shift) with the thumb.
+- Navigation is prioritized, arrows are right below the home row.
+
+## PC/Mac toggle
+The default setup is for Norwegian keyboard setting(not colemak variants) on a PC(Windows or Linux). Use the Mac/PC toggle button to switch between OSX and PC setup. The settings will be reverted to PC setup each time you restart/connect the keyboard.
+
+## Layers
+Numbers and function buttons are on their own layers. The easiest way to switch layers(at least with my hands) in this setup, is to push your hand right below the little finger, on the layer switches. You will then have all your fingers free to type numbers or press function buttons.
+
+## Shift-key
+Tap for the next character to be shifted, hold down for regular shift functionality
+
+## Layout
