For whatever reason, the shulker box EnumDirection isn't being retrieved properly, so AnyChest will only trigger on shulker boxes that would not be able to open if placed downwards (opening upwards). Silentchest and anychest will work, though.
Suppressed a few deprecation warnings that don't make sense to keep.
If you do use my fork of OpenInv's API, it's not yet stable (specifically, IAnySilentContainer), and will change a little more as I polish things up.
* Fixed anychest message spam
* Changed AnySilentContainer again to reduce duplicate checks
* #isAnyContainerNeeded should be checked before calling #activateContainer
* reorganized ifs for doublechest creation into reverse-order if elses to prevent creating extras when someone's broken Minecraft and put 3+ adjacent to each other
* Fixed incorrect block being checked for anychest in 1.11
* Progress on SilentContainerShulkerBox (we're getting there!)
anychest and silentchest aren't quite at 100% after all these changes, but it won't be a priority to revisit logic until shulker boxes are done
