Backends now have to send input to the given `chan::Sender<Event>`. They send these events from a separate thread, allowing selection between input and callbacks. This currently breaks the BearLibTerminal backend, which requires all calls to come from the UI thread. This might not be super-safe for the ncurses backend also. We hope that input and output are separate enough that they can run concurrently without problem.
