How to use padlock:
1. Add "on_padlock_place = function(player, pos, owner)" to the node definition.
The function should check, if a padlock is present.
If the padlock is already present, it should return false.
Otherwise it should add the padlock and return true.
2. Add "on_padlock_remove = function(player, pos, owner)" to the node definition.
The function should check, if a padlock is present.
If the padlock is missing, it should return false.
Otherwise it should remove the padlock and return true.
3. Add node to the "padlockable = 1" group (optional).
4. Add "ch_core.dig_padlock(pos, player)" to the can_dig before returning true.
(This function will call on_padlock_remove to test and remove a padlock.)
