Crate Lock Fix

Have you ever wondered why you couldn't reinforce or lock crates? Well, with this mod you now can. 

 

Due to how the crate entity is coded, it ignores any block behaviors and item interactions. In essence, it supports only inserting and retrieving actions. I've added some logic before these actions to check for plumb & square and padlock interactions. I've tried to make it as intuitive as possible.
