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.
Maven's fine with it, but it is bad practice.
OpenInv still modifies plugin.yml in OpenInvPlugin. It should really be done via the Assembly Plugin, but it works and I am lazy.
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.
