I've added an integration for the EntityPlayer class to my fork of the mod, and wonder if you would like a PR to add it or if I could release the changes.

The integration allows reading the main and armor inventories, offhand item, and player experience data. I needed the inventory stuff for a Metroid Prime 3 style security station that uses a sensor to scan for prohibited items in a player's inventory (among other things).

Also, does the integration stuff work from a separate mod that references this one? I could make an addon that adds this and other integrations (like Cosmetic Armor).
