[Keyboard] Create KBDFans directory (#5025)

* move over kbd19x into the kbdfans directory

* move over kbd4x into the kbdfans directory

* move kbd66 into the kbdfans directory

* move the kbd6x into the kbdfans directory

* move kbd8x into the kbdfans directory

* move kbd75 into the kbdfans directory

* move kbd67 into kbdfans directory

* add a fairly sparse readme for kbdfans directory

* update make instructions for keyboards and add the Complete Newbs Guide to readmes that was missing it

* get kbd75 compiling again

* remove repetitive #defines of KC_NO and KC_TRNS when QMK_KEYBOARD_H is already included in KBD75

* add links to kbdfans readme

* fix some readme formatting

* there is no reason to have two different keymaps with such a small difference, condensing to one

* turning on backlights by default

* enable backlight by default for kbd66

* noticed that the kbd75 had caps lock led code in every keymap. Moved it out to the keyboard.c so everyone can partake.

* Update keyboards/kbdfans/kbd66/readme.md

+## Othi's Universal HHKB keymap
+
+### Goals
+- Colemak layout. If you don't use Colemak then you'll need to also change the arrow key bindigns in other layers
+
+- Vim-like navigation layer so you can use vim binding arrowkeys in non-vim environment
+
+- Good modifier support so you don't have to hold 14 modifier keys at the same time
+
+- RGB indicating layer change(only work with plain colors so far, don't put your rgb to pulsing or any non static animation)
+
+### Layers
+- **CL:**
+
+	The base layer, default is Colemak
+
+- **NM_MODE:**
+
+	Vim-like arrowkeys in the home row, it's `LHNE` for *JENK Colemak* and `HJKL` for *QWERTY*
+
+	Also `HOME`, `END` and next/prev word (`Ctrl + Left/Right`) in `0, 4, w, b` like in vim
+
+- **VI_MODE:**
+
+	The same as `NM_MODE` but with `KC_LSFT` held down for mostly highlighting
+
+- **ACCENT + ACCENT_CAP:**
+
+	Function row and Unicode characters
+
+### Modifiers and Tap Dance keys
+**LHS:**
+
+- Any Tap Dance key with the format of `TD(XXX_NM)` act as normal XXX modifier upon hold, but will hold **and** put you to `NM_MODE` when double click hold(a tap before the hold)(eg you can produce `Alt + PgUp` by pressing `Alt + Alt + U`)
+
+- `KC_TAB` acts as both `KC_TAB` on tap and `KC_LGUI` on hold
+
+- R3 CapsLock acts as both `KC_BSPC` on tap and `KC_LCTL` on hold
+
+- Holding `KC_Q` also puts you into `NM_MODE`
+
+- Holding `KC_F` puts you into `VI_MODE` for fast function keys
+
+**RHS:**
+
+- 3 keys `KC_SCLN`, `KC_DOT` and `KC_SLSH` in `CL` layer can also be held down for respectively `KC_LCTL`, `KC_LSFT`, `KC_LALT` for easier 2-hand modifier holding
+
+- Right modifiers hold the selected modifier with `KC_LGUI` at the same time, mainly for i3wm, you can change this to whatever combination you want
+
+### Misc. functionalities
+
+**Unicode:**
+
+- In case the keyboard output the 4-digit codepoint instead of the actual unicode, you need to change the rewrite input mode of the keyboard into the EEPROM(you only have to do this if the EEPROM was cleared or your current machine use another unicode compose method other than IBus/Linux's `Ctrl + Shift + U`). Change the corresponding Input `void eeconfig_init_user(void)`. See [this](https://docs.qmk.fm/#/feature_unicode) for availble input modes.
+
+- **NOTE:** make sure to keep your qmk env up to date with upstream
