Part 1 of making inventory work again in the 1.19.1 (RC) client. Implemented the FetchInventoryDescendents CAPS handler. But currently returning empty folder details.

So this commit doesn't actually fix inventory in that client, it just stops the "loading" message being displayed forever next to a folder, and instead shows empty folders.
Next part will be to fill in the details of the items in the folders.
