Fix keyboard event detection

[Plonq]

To be honest I'm not sure whether this is the correct way to fix this, but it seems that #101 is caused by cd52f9f which moved the keyboard event handling to use Event::DeviceEvent instead of Event::WindowEvent -> WindowEvent::KeyboardInput. In my testing Event::DeviceEvent is not fired when pressing keys (on macOS). This doesn't revert the above commit, it merely moves the code to use WindowEvent::KeyboardInput instead.

Fixes #101

Note: doc check seems to be failing due to pre-existing typo

is there a new release coming soon that might incorporate this fix?
