Before, only KeyEvent::code_point took the user's keyboard layout
into consideration, while KeyEvent::key was hardcoded QWERTY. This
affected, among other things, Vim Emulation.
Now, KeyEvent::key respects the user's keyboard layout, so will be the
same as KeyEvent::code_point for visible (alphanumeric + symbol) keys.
