* Switch Quefrency back to I2C (#6161 fixes the lag)
* Update Quefrency keymap
* Add reset and EEPROM reset keybindings so these tasks can be performed
separately, rather than relying on Bootmagic Lite, which performs both
tasks at the same time.
* Move Caps Lock from Fn+Ctrl to Fn+Tab since Fn+Ctrl is sometimes used
as part of a more complex keybinding, whereas Fn+Tab is always safe.
* Update KBD67 keymap
* Add reset and EEPROM reset keybindings so these tasks can be performed
separately, rather than relying on Bootmagic Lite, which performs both
tasks at the same time.
* Move Caps Lock from Fn+Ctrl to Fn+Tab since Fn+Ctrl is sometimes used
as part of a more complex keybinding, whereas Fn+Tab is always safe.
* Move Menu to a layer tap on the Fn key since that's a more natural
location.
* Update 60% Tsangan HHKB layout
* Move Caps Lock from Fn+Ctrl to Fn+Tab since Fn+Ctrl is sometimes used
as part of a more complex keybinding, whereas Fn+Tab is always safe.
* Update 60% ANSI split backspace/right-shift layout
* Add reset and EEPROM reset keybindings so these tasks can be performed
separately, rather than relying on Bootmagic Lite, which performs both
tasks at the same time.
* Move Caps Lock from Fn+Ctrl to Fn+Tab since Fn+Ctrl is sometimes used
as part of a more complex keybinding, whereas Fn+Tab is always safe.
* Switch Quefrency from flaky I2C back to serial
* Lower mouse wheel speed on Quefrency slightly
* Migrate common settings to userspace
* Enable Bootmagic Lite for consistent reset to bootloader.
* Turn off some undesired features across all keyboards.
* Remove EEPROM reset keybinding from all keyboards since Bootmagic Lite
also does an EEPROM reset.
* Set backlight and underglow increments consistently across all
keyboards since lots of them like to override the deafults.
* Set mouse keys consistently across all keyboards.
* Update function layer keymap images
* Set Quefrency bootloader correctly for Elite-C
