[Bug] Many Super hotkey combinations do not work under Windows 10

[tvollstaedt]

Didn't check other OS'es, but on Windows 10, ueli does not seem to recognize Super+Space, Super+Plus, and many more. That's probably because they are already taken by the OS. We should remove the ones that are not valid or show an conflict message to the user.

Getting this working will require using a WH_KEYBOARD_LL hook within some windows-specific native node module. Electron's globalShortcut ultimately calls RegisterHotKey on Windows, which unfortunately fails for most Win + Key hotkeys already registered by the windows shell. See electron/electron#9206 Here's an example https://github.com/MarshallOfSound/node-lowlevel-keyboard-hook-win

This can be tricky to get right and it's a common issue in other launchers e.g. Wox-launcher/Wox#2445

Perhaps the best example of getting this to work well in practice is the PowerToys Run launcher from Microsoft themselves - based on the Wox launcher but crucially does support Win + Key hotkeys unlike Wox proper.

Also unlike most other launchers it captures hotkeys when there's a privileged window in the foreground (by hooking the keystrokes in a subprocess running as Administrator and forwarding events to the non-privileged main UI process) and handles focus stealing well.

Closing this issue as I don't see a way to fix it.
