Feature: Support for shortcut keys

[redphx]

With the rise of using 8bitdo Micro Gamepad as a page turner (it acts like a Bluetooth keyboard), I think it would be useful if NickelMenu adds support for activating its features by pressing a key/combination of keys. For example: taking screenshot by pressing a button on the controller.

I'm fine with creating a standalone mod for NickelMenu, but it'd be better if this feature can be integrated directly into NickelMenu.

Thanks.

I'd be willing to take this as an option prefixed with experimental_.

Here is the syntax I'm going to use. What do you think?

experimental:keybind:Ctrl+S:nickel_screenshot:capture

That works, but it might be easier to just take raw keycodes and let users look it up themselves (you'll need to for most bluetooth controllers anyways).
