Fixed MultiCrafters power output

[JojoFR1]

Power now outputs correctly (but it stop when all the power is used and reach 0 in battery, need to have a positive power input/power storage for the block to works) and changed the power bar to show output (might need to find a way to update the bars depending on the current recipe)

It seems like its the ConsumePowerDynamic that fixed everything not sure tho

Added some variable, don't know if they're useful

I used a global import by accident, my IDE is set up like that (I can change if that bother you)

And I don't really know exactly what I did, it's 3 hours of works so I let you read the changes
