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.
