API access to Compendium

... because, well, wouldn't that be really handy? E.g. an automatic wandering monster script? Or a spellbook generator. Or lots of other great stuff!

It'd be nice if we could get some access to the Compendium via Sheet Workers; for example, when importing Pathfinder monsters, it'd be nice if I could search for feats so that I could add in the description, like I can when drag-and-dropping a feat directly. Really, we'd just need two functions, tops: One you pass a category name and an item name, and it returns an object with the same properties you'd get if you did a drag-and-drop of the first item that matches that search criteria. One you pass a category name, and it returns an array of all the names of the items in that category (bonus: don't pass a category, get a list of categories)
