Remove the rematch button

It only creates annoyed people. People demanding a rematch get annoyed when denied one. People never wanting a rematch get annoyed by people demanding it. A feature that creates a bad mood should not exist.

I never experienced a 'bad mood' from it myself. I enjoy the ability to rematch against an opponent that I just had a fun or challenging game with. It's easy enough to decline and there's no obligation to accept.
