[FEATURE] Enter reverse configuration in each configuration.

[davidjimeneztv]

It would be great to have an option to define whether a cube should function in the usual way (starting the counter when it’s filled) or in reverse (starting the counter when it’s empty).

This way, there would be no need to restart the plugin and/or server every time you want to switch modes, and you could have two cubes for playing.

For example, this is quite useful when there is more than one streamer on the same server playing, and one wants to fill the cube while the other wants to empty it.
