Config settings to require items for motor rotation

[copygirl]

Suggestion:

motorRotationWrench=true/false
motorRotationItem=<list of items>

If any of these are set, empty hand rotating is disabled. If the wrench setting is turned on, it would make any item that implements IToolWrench able to rotate it. The item setting is a list of items, separated by ; or , with optional damage value, like id:damage. Any of these items can be used to rotate the motor as well.
