Add a feature to clear hotkeys

[Atrello]

I want to be able to run the software and have no hotkeys at all, could there be a button so I could clear it so nothing will pause the video?

I can work on adding better support for this, but I found a workaround for now that seems to work. If you click the hotkey input box and then while it is waiting for the new hotkey you press the Windows key, it will clear out the hotkey so that not hotkey exists.
