plz add oxide hook OnLootEntityEnd to ContainerIOEntity like in StorageContainer

As a general guideline, I suggest you share how you intend to use the hook. This allows people to sanity check if the hook you requested is the best way to solve your original problem, as well as help you figure out an alternative that you can do with existing hooks so you dont have to wait for an Oxide patch. It also gives people like me motivation to help make your cool idea possible (otherwise I am busy implementing other own ideas and will not likely bother).
