Non US keyboard layouts unsupported for hotkey registering

I think at the moment Controlcast doesn't correctly read non US keyboard layouts when setting up a hotkey.
Whenever I enter a key/combination containing umlauts (äöü) or ß and ´, the last of which are located directly right of the zero on the keyboard for my German layout, Controlcast registers a different key.
OBS seems to support the German layout.

For example:
strg + alt + shit + ß (which is my shortcut to start the stream)

is registered as
strg + alt + shit + [

To get a [ on the German layout, I'd need to enter:
strg + alt + 8

I never tested with a non-US keyboard layout. I will attempt to support multi-language layout.

The fix for #12 worked, but since / * + and , on the numkey seem to be tied to the non-US (in my case: German) keyboard layout as well, multi-language layout support would be the next logical step to complete full accessibility to the num keyboard. Thanks!
