Screwdriver API
---------------
The screwdriver API allows you to control a node's behaviour when a screwdriver is used on it.
To use it, add the on_screwdriver function to the node definition.
on_rotate(pos, node, user, mode, new_param2)
^ pos: position of the node that the screwdriver is being used on
^ node: that node
^ user: the player who used the screwdriver
^ mode: screwdriver.ROTATE_FACE or screwdriver.ROTATE_AXIS
^ 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 = screwdriver.rotate_simple to allow only face rotation
Stairs API
----------
The stairs API lets you register stairs and slabs and ensures that they are registered the same way as those
