Fixed a bunch of bugs related to the Graveyard screen.
- (Bug) When the player is not in the current leaderboard sort, the camera would focus on the spot to the left of the first grave.
- (Bug) Graveyard now defaults to the Player sort category instead of Global.
- (Bug) The grave customization option is now disabled if the player does not have a grave present in the current sort list. This only applies to Global sorting.
- (Bug) Fixed a bug where the game would crash if the player went directly to the Graveyard screen, entered the grave customization menu and then backed out of it. This was due to the player not having a gravestone in the current sort list.
- (Bug) Global sorting the Graveyard screen would sometimes allow the graves to scroll beyond the first and last gravestones.
