- do the scancode to keyboard code lookup for the grave key, so that we can show users the correct keyface for the key, rather than forcing it to "`".  Note that if a game is using SDLK_* for its KB mapping then after this change on some keyboards the top left key will no longer be mapped correctly with the old data.
