Now that we've got our menus in place, we need a way for each player to navigate them. we don't want the player who's on mouse and keyboard to impact the other who's using a gamepad (should that be the case) so we'll set it up so they don't interfere.
Unreal engine doesn't have very good UMG registration for gamepads... but i've found a little work around that should work for what we need :D
