ripoff of the ergodox one, but rewritten as a state machine.

* debugged some, got key repeat working

* moooar coverage

* moooar coverage

* regular vis mode

* basically done with basics.

* some refactoring

- common movement sequences into helper function

* stdized on cmd-left/right instead of ctrl-a/e

sadly. as there's no reliable shift-ctrl-e
