Keymap: Initial PR for contributing my ortho_4x12 community layout. (#3853)

* Initial keymap with no BL and with Ctrl and Enter on the home row.

* Removing alternative layouts (Dvorak etc.).

* Putting Enter back in the default position, moving Esc next to Alt.

* Replacing grave with del.

* Adding a numpad layer.

* Adding operators and a triple zero to the numpad layer.

* Swapping Alt and Win.

* Updating to use new audio macros.

* Removing numpad layer and changing left space to MOD_HYPR on hold.

* Adding configurable 'clicky keys' feature.

* Cleaning up clicky conditional logic.

* Turning on backlight support and mapping backlight keys in the adjust layer.

* Enabling backlight functionality.

* Adding Adventure time theme song; increasing fake clicky randomness.

* Cleaning up layer constants in my Planck keymap.

* Initial implementation of porting my Planck keymap to a Let's Split.

* Updating keyboards/planck/keymaps/josh to use declarations from new work on master.

* Updating keyboards/lets_split/keymaps/josh to use declarations from new work on master.

* Work in progress migrating Planck and Let's Split keymaps to a community keymap.  Everything is working but Planck backlight.

* Fixing rules.mk to enable backlight & audio correctly on Planck PCBs.  Cleanup.

* Tweaks to get Let's Split working with my community layout.

* Switching to use EE_HANDS in my Let's Split build.

* Adding vitamins_included makefile options to my ortho_4x12 layout.

* Fixing planck/rev6 build -- backlight must be disabled.

* Removing I2C from my rules.mk and addressing it in the config.h instead.

* Moving community layout directory to my reddit username.  :D

* Adding a test encoder function; making lower left a media key and moving esc to a mod tap on ctrl.

* Commenting out -flto in the compiler flags for the vitamins_included keyboard (couldn't figure out how else to turn it off).

* Changing rotary encoder to control media volume.

* Changing backlight and clicky defaults to max brightness no breathing and a low pitch click.

* Initial implementation of backlight flickering.

* Updating my README.md

* Adding LINK_TIME_OPTIMIZATION to the vitamins_included/rev1 as a rules.mk feature.

* Reverting keyboards/vitamins_included/rules.mk to master and using 'filter_out' in my layout instead.

* Adding tested boards to the readme for my layout.

* Per drashna, removing redundant clicky implementation and cleaning up headers.

* Removing an extra include from my keymap.

+# Josh's 4x12 layout
+
+Notable features:
+
+* Esc is Ctrl on hold
+* Left space is `MOD_HYPER` on hold
+* Backspace is still backspace on `RAISE` and `LOWER`
+* Faux clicky controls are on the arrow keys on the `ADJUST` layer, and the backlight controls are directly above that
+* Backlight breathing is disabled; backlight flickering is implemented instead
+* Colemak and other layouts are thoroughly disabled
+* Rotary encoder controls media volume on base layer
+
+This layout has been tested on:
+
+* Let's Split (rev 2)
+* Let's Split Vitamins Included (rev 1)
+* Planck (rev 4)
+
+It builds for the Planck rev 6 but has not been tested yet.
