BlockGrave: use same logic to determine player name as TileEntityGrave (

#19)

BlockGrave#getPlayerRelativeBlockHardness now uses EntityPlayer#getGameProfile#getName instead of EntityPlayer#getDisplayName. The latter may change if the player has a "nickname" (see: FTB Utilities), while the former should never change.
