* 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
Mostly based on Mbaxter's AbstractionExamplePlugin
Compiling OpenInv for a specific version is very easy - just compile the correct module.
Compiling for a set of versions is slightly more complex. You'll need to use a profile for the versions you want to compile. Provided profiles are latest, modern - versions 1.7.10+, and all. For more information, check out the Maven guide http://maven.apache.org/guides/introduction/introduction-to-profiles.html
This commit doesn't change anything with the plugin itself, but it makes it loads easier for people to maintain and compile their own version without destroying backwards compatibility.
