Add a gamerule for commands to enable remote commands without a player being present.

Add a game rule to commands to activate commands remotely without a player being present. Example: “gamerule CommandBlockcheck limit 1000” or something similar, to make it easier to activate commands without the player having to stay inside a chuck. If you don't want this, you can disable it with “gamerule CommandBlockCheck limit 0,” which adds more creativity and helps if someone is far away for the command to be activated.
