Title: Changes to the left-clicking with the Chisel in-hand...

Basicly, the Chisel as item can't break ANY blocks anymore, it's all handled through Forge-events.
I don't think there are needs to check, if the config-option for this is enabled / disabled, so the item can still break blocks in the world... Seems useless..
