Harry Mills 8ec2269519 Add magic backspace to my layout (#2758)
* Add Haegin's keymap

* Potential improvements to the keyboard

* Add haegin minidox layout

* Add Haegin's keyboard to ergodox layouts

* Update Haegin's minidox keymap

* Add home, end, and page up and down

* Magic Backspace

Backspace still acts as control when you hold it down, but if you tap it
twice and hold it's a held backspace. Tapping it more than twice it
continues to act as backspace, but it deletes more characters with each
tap with the quantity deleted based on the fibonacci sequence.

* Switch to deleting words after 4 taps

When hitting backspace, after 4 taps this switches to deleting by word
because if you're hitting backspace that frantically you must need to
delete a lot of stuff. Holding backspace after 4 taps will delete words
in the same way that holding alt+backspace deletes words on a normal
keyboard.
