Durability 0 when adding auto close to partially used spanner

[FireAngelDth]

Looks good to me. With the auto spanners they get 10% of the max durability. So instead of 100 you got 300

Made auto door spanner have more durability than before, and the amount of durability is relative to the base amount of durability (10% of base). Also auto door chisels can have durability traits too.
