Add the following for rolling dice:

• <Dice> argument: Accepts a string and converts it into a Dice object. If a Statted is supplied to the command, then any variables matching a stat that the creature has shall be replaced with that stat, otherwise the variable shall be replaced with 0.

• /roll <Dice> command to roll dice, shall accept any stat supplied, supplementing with 0 if the user's active character does not have that stat or has no active character.
