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

+# German Layout for the ErgoDox
+
+This layout is inspired by the "kinesis-qwerty-mod" from benblazak's
+[ergodox-firmware](https://github.com/benblazak/ergodox-firmware), as well as by the "german" layout from the 
+[qmk_firmware](https://github.com/qmk/qmk_firmware).
+The goal was to have a layout that is pretty close to an ordinary German
+keyboard, so I don't have to make adjustments on the operating system level
+and I keep some of the muscle memory to use a regular keyboard.
+
+Modifications I made with regard to the aforementioned layouts:
+
+* The key layout is pretty close to the layout of a German Kinesis Ergo Elan.
+  The only exception I made is that I reversed the "up" and "down" cursor keys,
+  since that feels more natural to me.
+
+* All layer changes are "momentary", i.e. they only last as long as the respective key is pressed.
+
+* I sacrificed the Hyper and Meh keys, which I don't use, and put layer change keys in their place.
+
+* I added a PrintScreen key which I use quite regularly for screenshots.
