* Set Quefrency bootloader correctly for Elite-C

* Update Quefrency layout to be more like HHKB

* Update KBD67 layout to be more like HHKB

* Add keymap for BDN9 macropad

+# bcat's BDN9 layout
+
+This is a simple macropad with seven keys and two rotary encoders. We use one
+encoder for volume and the other for backlight brightness. Six of the keys are
+F keys (for gaming, since I use keyboards without function keys normally), with
+the remaining key a layer toggle that switches the function keys between F1-F6
+and F7-F12.
