Screwdriver: disallow rotation with on_rotate = false

This allows nodes to default to full-disallow rather than full-rotation in such a situation.

* `new_param2` the new value of param2 that would have been set if on_rotate wasn't there
* return value: false to disallow rotation, nil to keep default behaviour, true to allow
it but to indicate that changed have already been made (so the screwdriver will wear out)
* use `on_rotate = screwdriver.disallow` to always disallow rotation
* use `on_rotate = false` to always disallow rotation
* use `on_rotate = screwdriver.rotate_simple` to allow only face rotation
