Tic-80: Keyboard mappings broken!

[frsgrn]

The TIC-80 thinks my nordic keyboard is American(or british).
Really annoying. I don't have this problem in 0.60

Same situation with Japanese keyboard.
I also don't have this problem in 0.60.3.

yes, we should read keyboard Keycodes instead Scancodes

Oddly enough, the browser version is a little better than the standalone but still have issues. With my Japanese keyboard, I can type "[" and "]" in the browser, but not ":", numpad keys, etc.
In the standalone editor, the numpad still doesn't react but "[", "]" and ":" all give wrong characters.
