Finalize current keymapping work:

- catchup with latest changes to pilot/keys.js
- the textinput adds a event.addCommandKeyEvent(...) to the input
- the onTextInput and onCommandKey event sent by the textinput are forwareded to the edtior which
  then forwards the input to the keybinding, which handles the input based on the current inputMode.
- the current inputMode can get changed by setting the setting "inputMode". Currently there are the
  modes "vim" and "emacs". If the inputMode doesn't match, the "default" mode is used.
