Newer version of Unity Input system, logo update

I upgraded to a newer version of the Unity input system, this is in preparation for the key rebinding.

Updated the Logo.

I don't expect this one to cause any issues, I've been playing on it for a few days, but please let me know if anyone sees any problems.

Also, please don't opt into the beta branch right now, there's nothing on it. I set one up very briefly to test but there's no build associated with it right now.

Thank you!
